libquesoglc0-0.7.2-10.mga7.armv7hl.rpm

Changes made from the "0.7.1" release to the "0.7.2" release:
-----------------------------------------------------------

* Bertrand Coconnier:

- Fixed bug #2019450 (added a workaround for open source drivers of the Intel
  chipsets : a bug in the drivers prevent a character to be displayed).
- Fixed a bug which caused some memory leaks when memory allocation failed
  during the update of the masters.
- Updated the demo in the examples: extrusion and ligthing have been added.
- Fixed glcGetFontMap() and glcGetMasterMap() so that their return is not null
  when a character is mapped in the font/master but its Unicode name is not
  stored in QuesoGLC database.
- Character codes out of range are now rejected when GLC_UCS1 or GLC_UCS2 are
  enabled. GLC_PARAMETER_ERROR is then raised.
- Fixed a bug that crashed QuesoGLC when trying to call glcGetFontMap() with a
  character not mapped in the font.
- Fixed a bug which caused the measurement caches not to be updated when
  GLC_RESOLUTION was changed by the users.
- Fixed a memory leak in the management of the texture atlas: when a font was
  deleted, the memory allocated to this font in the atlas was definitely lost
  instead of being given back to the texture allocator.
- Fixed a bug which did not include trailing spaces in the calculation of
  bounding boxes.
- Fixed a bug which caused artifacts when rendering glyphes that extend beyond
  the EM square.
- Fixed a bug which prevented letters l and i to be displayed at small scales
  when GLC_HINTING_QSO and GLC_TEXTURE were enabled.
- Side effect of the above bug fix : the antialiasing is improved for most
  characters since they are no longer located against the edges of the texture.
- Fixed a bug in glcGenFontID() which could return the ID of an existing font.
- Fixed a race condition in glcGenContext()
- Function glcGetStringCharMetric() now returns metrics in global string
  coordinates (otherwise the kerning can not be measured)
- Fixed bug #1987563 (Kerning does not work when GLC_GL_OBJECTS is enabled)
  Thanks to GenPFault for the bug report.
- Fixed bug #2012579 (Mac OSX Leopard compiling bug) - Thanks to Michael Strobel
  and Tim Baumgartner for the bug report and the patch.
- Negative values passed to glcResolution() now raise GLC_PARAMETER_ERROR
- Fixed bug #1980982 (Checks for MinGW in the configure script are incomplete)
- Feature request #1947346 : added files for pkg-config (thanks to Giel
  van Shijndel and Dennis Schridde for providing them)
- Fixed bug #1947464 (Warnings are generated when compiling with gcc option
  -Wstrict-prototypes)
- Fixed bug #1935557 (Fonts are not rendered correctly when the resolution is
  changed using glcResolution).

Changes made from the "0.7.0" release to the "0.7.1" release:
-----------------------------------------------------------

* Bertrand Coconnier:

- Fixed the bugs #1852883 and #1890660 (VBOs had an erratic behaviour on some
  Mac OS X platforms and Intel X3100 gfx cards under Linux).
- Removed the workaround for bug #1852883

Changes made from the "0.6.5" release to the "0.7.0" release:
-----------------------------------------------------------

* Bertrand Coconnier:

- Added a workaround for bug #1852883 : VBOs are disabled on Mac OSX platforms
- Fixed a bug in the measurement routines which caused the advance vector of
  strings to be wrongly computed.
- Simplified a bit the GL state management (enabling of GL_TEXTURE_2D should now
  be done by the user when the rendering style is GLC_TEXTURE)
- Updated GLEW source code to release 1.5.0
- glcGetFontMap() and glcGetMasterMap() now return GLC_NONE if the font/master
  does not map 'inCode'.
- Updated test7 in order not to report an error when testing fonts which defines
  a space character with no width.
- glcGenFontID() now creates an empty font in order to reserve the ID for a
  future use. The new ID can be freed by deleting it with glcDeleteFont().
- Measurement datas of glyphes are now cached in order to accelerate the
  measurement commands when GLC_GL_OBJECTS is enabled.
- Fonts which belong to the same family are now grouped in the same master.
- Added project files for Microsoft Visual C++ 2005
- Fixed bug #1856336 (glcFontFace reports GLC_RESOURCE_ERROR on Windows when
  selecting the "Arial Regular" font face).
- Removed explicit calls to glGetString(GL_VERSION) and
  glGetString(GL_EXTENSIONS) in glcContext() since GLEW already takes care of
  that.
- Fixed bug #1843710 (Code to handle missing FTC_Manager_* is broken).
- GLC_LINE mode now uses Vertex Buffer Objects (VBO) whenever the gfx card
  supports them
- Added extension GLC_QSO_buffer_object to report the use of VBOs and PBOs
  through glcGeti(GLC_BUFFER_OBJECT_COUNT_QSO) and its corresponding call to
  glcGetListi(GLC_BUFFER_OBJECT_LIST_QSO, int).
- GLC_TEXTURE mode now uses Vertex Buffer Objects (VBO) whenever the gfx card
  supports them
- Fixed bug #1834256 (part II) : The configure script now guesses the correct
  flags to use in order to cross-compile QuesoGLC for MinGW32
- Fixed bug #1834256 (part I) : An option has been added to the build scripts
  in order to disable the build of tests and examples 
- Fixed bug #1640256 (RTL scripts were wrongly supported and the fix introduced
  for release 0.6 was actually a partial fix).
- Improved tests coverage (all GLC functions are now tested at least once with
  all its legal attributes)
- Spacing characters have now their own caching system when GLC_GL_OBJECTS is
  enabled.
- Code refactoring between glcRenderString() and glcRenderCountedString() in
  order to maximize common code for easier maintenance.
- Display lists are now called earlier in glcRenderChar() in order to minimize
  useless overhead.

Changes made from the "0.6" release to the "0.6.5" release:
-----------------------------------------------------------

* Bertrand Coconnier:

- Rendering and measuring routines now skip control characters instead of
  having a random behavior about them.
- Fixed bug #1820546 (glcRenderString("") displayed the last rendered string
  minus its first character)
- Fixed bug #1821219 (Blank characters (i.e. spaces) were wrongly transformed
  into null characters)
- Removed the use of FcStrSet and FcStrList objects for the catalog list. Use
  object __GLCarray instead.
- Fixed bug #1814773 (QuesoGLC uses the system library GLEW whenever
  possible. Otherwise a copy of GLEW is automagically built and embedded with
  QuesoGLC)
- Fixed bug #1812058 (QuesoGLC uses the system library FriBiDi whenever
  possible. Otherwise a copy of FriBiDi is automagically built and embedded with
  QuesoGLC)
- Fixed bug #1754660 (actually a partial fix. See explanations on bug #1754660
  on SourceForge.net)
- Renamed some type names (FT_ULong, FcChar8, ...) in order to make them more
  portable.
- Minimized the use of pthread_get_specific()/TlsGetValue() when only one thread
  is used and when ELF TLS is not available, since calls to those functions are
  expansive.
- Removed the useless QUESOGLC_STATIC_LIBRARY
- Modified QuesoGLC threading implementation in order to use ELF TLS when
  available. This allows to discard the expansive calls to pthread_get_specific.
- Removed the useless QUESOGLC_VERSION macro
- Removed __glcFaceDescGetCharMap() which were buggy for some fonts. Now uses
  Fontconfig patterns instead. This fixes a bug which created a new font for
  each newly rendered glyph.

Changes made from the "0.5" release to the "0.6" release:
-----------------------------------------------------------

* Bertrand Coconnier:

- Fixed bug #1640256 : the advance vector now supports RTL strings
- Fixed a bug by disabling kerning when two successive characters of a string
  are not rendered with the same font.
- Modified __glcFaceDescGetFontFormat() to use FT_Get_X11_Font_Format(),
  whenever available, to detect the font format.
- Fixed a bug which caused a character that was not mapped to any font to be
  rendered wrongly the second time it is displayed when GLC_KERNING_QSO is
  enabled (bug reported by Brandon Casey).
- Added a test in the tests directory that checks if empty strings are
  correctly handled by the functions of QuesoGLC (no crash, no unexpected
  errors, no memory leaks).
- Modified the texture routines so that QuesoGLC tries several sizes of texture
  before giving up when rendering in GLC_TEXTURE mode with GLC_GL_OBJECTS
  disabled.
- Fixed global commands so that they can not execute GL commands since we can
  not make sure that the relevant GL context is bound to the current thread
  when a global GLC command is executed.
- Changed __glcSaveGLState() and __glcRestoreGLState() so that only a minimal
  part of the GL state is saved before the rendering commands are issued.
- Removed redundancy in the calls to glBindTexture() when the GLC_TEXTURE
  rendering mode is used.
- Removed the visibility test based on bounding boxes since it slowed down
  everything and the user can perform this test himself by using measurement
  commands.
- Modified immediate texture rendering to take advantage of pixel buffer
  objects (PBO) whenever the gfx card supports them.
- Optimized the rendering code so that the conversion from 26.6 fixed point
  coordinates to GLfloat is partially done by the GPU by using glScalef().
- Cleaned up some internal transactions between private functions in order to
  prevent back and forth translation between a font ID and its corresponding
  structure __GLCfont.
- Code cleanup :
  * Fixed the signed/unsigned comparisons
  * Removed unused function parameters
  * Renamed the structure __GLC* instead of __glc* for more consistency with
    Mesa.
  * Added some comments
- Fixed the computing of the bounding box of a glyph when GLC_EXTRUDE_QSO is
  enabled.
- Optimized the de Casteljau algorithm by splitting it into 2 specialized
  subroutines (one for conic Bezier curves and the other for cubic Bezier
  curves).
- glcDeleteContext() does not destroy GL objects anymore. This is done because
  we can not be sure that the GL context that is current (if any) is the one
  that contains the GL objects associated to the GLC context that we are
  destroying. Documentation is updated accordingly. (Issue pointed out by
  Brandon Casey).
- Removed some calls to __glcGetCurrent() that could cause operations to be
  performed on the wrong context or to fail when they should succeed (issue
  pointed out by Brandon Casey).
- Removed glPush/PopClientAttrib() and use glIsEnabled() instead since that is
  much faster.
- Vertex arrays are now used to render characters in GLC_TRIANGLE mode.
- QuesoGLC now uses GLEW, the OpenGL Extension Wrangler, to manage OpenGL
  extensions.
- Removed the master object, uses FontConfig API instead. This allows to not
  load all the masters in memory : masters are now loaded "just in time" which
  reduces the memory footprint of QuesoGLC. Furthermore, when GLC_AUTO_FONT is
  enabled, QuesoGLC takes into account the user preferences for FontConfig.

* Brandon Casey:

- Declared unused arguments with compiler attributes in order to fix compiler
  warnings and allow some optimization.
- Rearranged glcGenContext() to avoid unlikely race.
- Moved the call to __glcConvertGLintToUcs4() before the GL state is saved in
  RenderChar(). This saves much GL work if the conversion of the character
  fails.
- Avoided strlen call by using return value of snprintf/sprintf_s in unicode.c
- Fixed __glcCtxQueryBuffer() so that it leaves the context unchanged on
  failure.
- Fixed calls to __glcCtxQueryBuffer() so that GLC_RESOURCE_ERROR is not raised
  twice on failure.
- Added header unistd.h to master.c since it is needed by access()
- Fixed test4 by supplying a valid directory for AppendCatalog/PrependCatalog
- Modified __glcConvertUcs4ToGLint() so that a variable that is only used for
  debugging is now conditionally compiled
- Simplified __glcRaiseError() testing of current error state
- Ensured at least one texture level is created by using a do {} while,
  otherwise when hinting is enabled and Xscale or Yscale are too small,
  sometimes no new texture is created and we render a portion of the previous
  image.
- Avoided free'ing NULL buffer in texture routines
- Fixed scalable rendering when using external display list
- Fixed the character measurement buffer which was not reset at each call of
  glcMeasureString() or glcMeasureCountedString(). So newly measured characters
  were continually appended to measurement array.
- Removed the call to __glcGetScale() in measuring routines since it is not
  necessary and breaks if hinting is enabled and rendering bitmap.
- Fixed kerning adjustment in __glcGetCharMetric().
- Moved point size adjustments into ofacedesc.c functions to mimic
  __glcFaceDescGetBoundingBox() 
- Replaced __glcFree() by free() when glc allocation functions didn't allocate
  the memory.
- Fixed glcExtensions string in test6.c
- Changed glScalef() call in unicode.c so that z dimension is not zeroed which
  breaks hinting.
- Fixed parameter type of __glcTextureGetImmediate() (GLsizei instead of
  GLuint).
- Replaced floating point multiplication by bits shifting.
- Enabled FT_OUTLINE_HIGH_PRECISION when building mipmaps.
- Avoided signed/unsigned comparison.
- Arranged extension strings in GLC_EXTENSIONS alphabetically (as per Section
  2.5 of GLC Specification Version 0.2 - 27 Oct 1996).
- Fixed Unicode functions (strlen() does not take into account the trailing
  '\0' character and a pointer was not dereferenced).
- Merged pitch and width rounding calculations.
- Fixed kerning measurement and rendering calculations
- Modified autoconf files so they build with version 2.57.
- Made QuesoGLC compile with Freetype library older than 2.1.8.
- Changed __glcFindIndexList() semantics to return address of separator
  occurrence.
- Fixed a test so that the GLC_CATALOG_LIST environment variable is now taken
  into account.
- Prevented advance past end of string during conversion between logical order
  and visual order so that zero length strings are handled properly.
- Removed NULL dereference after FcPatternGetString().
- Fixed texture atlas coordinate calculation.
- Improved texture rendering by optimizing the bounding box coordinates
  calculation.

Changes made from the "0.4" release to the "0.5" release:
-----------------------------------------------------------

- Fixed the #include so that QuesoGLC can be built with MSVC++
- Added an attribute stack to save and restore the GLC state variables.
- Added a matrix stack for GLC_BITMAP_MATRIX.
- Added support for kerning.
- Added support for the FreeType cache sub-system.
- Force thread-safety for included libraries.
- Fixed a bug where glcGetMasterc() returned silly values for
  GLC_FULL_NAME_SGI and GLC_VERSION attributes.
- QuesoGLC is now compliant with the Unicode Bidirectional Algorithm (UAX#9)
  thanks to Fribidi.
- Added the ability to extrude the characters.
- A texture atlas is now used for GLC_TEXTURE rendering style.
- Improved the speed for display list rendering by moving out some stuff that is
  only needed for immediate mode rendering.
- QuesoGLC now tries to re-use as much as possible the texture generated for
  immediate mode rendering.
- The OpenGL version is now checked and the texture rendering behaves
  accordingly.
- Environment variables GLC_LIST_SEPARATOR and GLC_CATALOG_LIST are now read by
  QuesoGLC. They supersedes GLC_PATH if defined otherwise GLC_PATH is parsed.
  (suggestion by Brandon Casey).
- Blank Unicode characters (that is character which are expected to be blank
  when drawn) are now managed according to the Unicode standards.
- Thomas Zimmermann greatly improved the building scripts.

Changes made from the "0.3" release to the "0.4" release:
-----------------------------------------------------------

- Modified the GLC_PATH parser code in order to use semicolon-separated lists
  for Win32 and colon-separated for POSIX platforms.
- Added a makefile so that QuesoGLC can be built under Win32
- Removed the pthread dependency for Win32
- Added a new __glcGlyph object that allow to cache the display list, the
  texture, the bouding box of a glyph. Those objects are managed by
  __glcFaceDescriptor which allow to keep the glyphes as long as the face exists
- Revamped the code in order to better encapsulate FT_Face in
  __glcFaceDescriptor and FcCharSet in _glcCharMap.
- The thread local storage is now released when QuesoGLC is unloaded
- Modified the python script that builds the character names database : the
  number of character names can be given as a command-line parameter.
- The master object (defined in omaster.h) now uses __glcCharMap instead of
  FcCharSet.
- Brandon Casey fixed the rendering commands so that the character sequence
  \<0> is not issued when glcRenderString is called with a zero length string
  (i.e. a string that only contains the null terminator) 
- Brandon Casey fixed the measurement commands so that they give correct values
  for the minimum y coordinate
- Brandon Casey changed the GL_TEXTURE_ENV_MODE to GL_MODULATE instead of
  GL_REPLACE in order to allow the user to change the transparency of the text
  by setting the alpha component with glColor4*()
- Brandon Casey fixed the GLC_BITMAP and GLC_TEXTURE rendering styles so that
  the complete set of GL_UNPACK parameters are set before the picture is
  uploaded in order not to depend on the user setting of those parameters
- Brandon Casey provided a patch to allow QuesoGLC to compile with FreeType libs
  older than 2.1.8 (winfonts were not supported before 2.1.8)
- Pablo Barbáchano provided a patch to allow QuesoGLC to use FreeType 2.2.x
  (const-ness added to some parameters of the callbak functions of
  FT_Outline_Decompose)
- Removed the stupid limit that generated GLC_PARAMETER_ERROR whenever some
  functions were called when the string type was GLC_UTF8_QSO (see below).
  Indeed a Unicode codepoint can be no higher than 0x10ffff and can thus be
  stored in a 32 bits integer in UTF-8 format.
- Uses GNU extensions of gcc where possible to implement the constructor and the
  destructor of the library (instead of _init and _fini)
- Fixed the crashes due to the removal of the combine callback of the GLU
  tesselator. The callback is now restored and compatible with the arrays of
  variable size (__glcArray)
- Quesoglc now uses autotools to build
- Thomas Zimmermann fixed the string measurement commands that did not return
  results that were consistent with those returned by glcCharMetric().
- Fixed a bug in glcDeleteFont() where the face was not closed before the font
  was deleted.
- Display lists are now managed at the charmap level instead of being handled by
  the masters. This allows a better management and optimizes the GPU memory
  management by deleting display lists and textures as soon as the corresponding
  glyph is removed.
- Charmaps now use binary search instead of linear search
- Texture mipmap levels in GLC_TEXTURE style are now built directly by QuesoGLC
  instead of using GLU. It should provide better rendering quality at small
  pixel sizes
- The z coordinate of bounding boxes is now also used to determine if a Bezier
  curve lies outside the viewport
- Calculations now use GLfloat instead of GLdouble
- Removed the useless third coordinate of the vertex array used for GLC_LINE
  and GLC_TRIANGLE styles
- Fixed a bug where the advance of a glyph that is skipped because it lies
  outside the viewport were not taken into account
- Unified the behaviour of the rendering and measuring routines so that the
  later now take into account the state of GLC_HINTING_QSO.
- Removed the file 'constant.h'
- Added the enumerant GLC_HINTING_QSO to the glEnable()/glDisable() functions
  to allow the user to activate hinting when glyphs are rendered at small pixel
  sizes. By default, hinting is disabled because it creates visual artifacts
  when the glyphs are animated.
- In order to accelerate the rendering of characters, glyphs which bounding box
  lies outside the viewport are now skipped.
- In GLC_TEXTURE mode, no mipmap is built anymore if the glyph is rendered in
  immediate mode (that is if GLC_GL_OBJECTS is disabled and the user is not
  building a display list).
- Fixed a bug in glcRenderChar() where the texture used in GLC_TEXTURE mode was
  deleted after the glyph was rendered if GLC_GL_OBJECTS was disabled. This
  could lead to unexpected results if the user tried to encapsulate the
  glcRenderChar() call in a glcNewList/glcEndList pair.
- In order to accelerate the rendering of glyphs in GLC_LINE and GLC_TRIANGLE
  modes, outline curves that lie outside the viewport are replaced by a
  piecewise linear curve that joins the control points.
- The criterion that is used by the de Casteljau algorithm is now computed in
  pixel distance rather than in object space distance whenever no display list
  is building. This leads to a more optimal number of vertices which depends on
  the actual size of the glyph on the viewport.
- Scaling of glyphs for the GLC_BITMAP style is now detected thus allowing to
  pass the correct character size to FreeType (instead of the fixed arbitrary
  size GLC_POINT_SIZE) when the character is rendered. This optimizes the grid-
  fitting of the glyph and provides slightly enhanced character rendering at
  small sizes.
- Transformation matrices that lead to degenerate cases for the GLC_BITMAP style
  are now correctly handled.
- The 'data' and 'length' members of __glcArray are now accessed through macros
  (GLC_ARRAY_DATA and GLC_ARRAY_LENGTH) instead of explicit pointer
  dereferencement thus providing some kind of encapsulation for the __glcArray
  object.
- Arrays that store the vertices and control points during the rendering of
  GLC_LINE and GLC_TRIANGLE styles are now handled by the context state. Hence
  they are not created and deleted each time a glyph is rendered thus saving
  memory allocation/deallocation.
- The buffer that stores the measured characters is now an array of variable
  size (__glcArray)
- Fixed a bug in measurement commands where bounding boxes and baselines did not
  take the GLC_RESOLUTION value into account.
- The de Casteljau algorithm now uses the chordal distance of the control points
  of the spline rather than the chordal distance of the midpoint of the spline
  to determine if the curve needs to be broken or not, thus leading to a better
  handling of antisymmetric cubic curves (such as S-shaped curves). This is also
  a more severe criterion : some spline curves may now be broken into more
  segment curves than before.
- Revamped the implementation of de Casteljau's algorithm : hard-coded limits of
  arrays have been removed. Data are now handled by arrays of variable size
  (__glcArray).
- Charmaps now use arrays of variable size (__glcArray)

Changes made from the "0.2" release to the "0.3" release:
-----------------------------------------------------------

- Fixed a bug in glcRenderChar(), glcRenderString() and glcRenderCountedString()
  that prevented the replacement code or the character sequence '\<hexcode>' to
  be displayed when QuesoGLC failed to find a font that maps a character code.
- A GLC_PARAMETER_ERROR is raised if the string type is GLC_UTF8_QSO and one of
  the following functions is called :
    * glcGeti(GLC_REPLACEMENT_CODE)
    * the callback function defined by glcCallbackFunc()
    * glcFontMap()
    * glcGetFontMap()
    * glcGetMasterMap()
    * glcGetCharMetric()
    * glcRenderChar()
    * glcReplacementCode()
- Fixed several issues that prevented QuesoGLC to compile and run on 64 bits
  platforms
- Improved the mechanism that determine the format of font files
- Added support for the GLC_SGI_full_name extension
- Fixed glcGetMaxCharMetric() where the maximum size of the characters were
  computed in EM units thus leading to wrong results if the different
  characters did not have the same EM square size.
- General management of header files has been moved to internal.h (most source
  files now just need to include a unique header file "internal.h")
- Modified glcResolution() so that the resolution of every font of the
  GLC_CURRENT_FONT_LIST is updated whenever glcResolution() is called
- The GLC_IS_FIXED_PITCH attribute is now managed per font, not per master
- The verification of master parameters has been moved to the specific function
  __glcVerifyMasterParameters(). This simplified the code
- The management of the header file assert.h has been moved to internal.h
- Fixed glcIsFont() so that it does not raise GLC_PARAMETER_ERROR when 'inFont'
  is not the ID of a font
- Fixed glcGetFonti() so that it returns the font attributes instead of the
  parent master attributes
- Fixed glcGenFontID() so that it returns sensible results when it is called
  several times in a row
- Fixed glcFontFace() so that the face of every fonts of GLC_CURRENT_FONT_LIST
  are set to the face identified by 'inFace' if 'inFont' is zero (previously
  only one face was modified when 'inFont' was zero)
- Fixed glcFont() so that the client state is left unchanged if an error occurs
- The UTF-8 support is an extension of QuesoGLC, hence the GLC_UTF8 enumerant
  has been appended with 'QSO' (like 'QueSO GLC extension'). The enumerant has
  also been modified which broke the ABI compatibility with version 0.2
- Brandon Casey removed the hard-coded limit of the charMap array for fonts
- Brandon Casey modified the allocation and the management of the
  measurementCharBuffer. It is now dynamically allocated instead of statically
  defined.
- Brandon Casey fixed a bug in glclogo.c where GLC_GL_OBJECTS was not disabled
  hence preventing the display lists to be correctly built.
- Brandon Casey modified testrender.c so that a box is drawn around the text
  rendered in GLC_BITMAP style in order to demonstrate proper rotation. This
  example is analogous to the test that shows failure of SGI's GLC to properly
  perform this operation (http://www.opengl.org/resources/features/fontsurvey)
- Fixed a bug in glcFontMap() which screwed the charMap array when a character
  was removed from the font map (bug reported by Brandon Casey)
- Textures in the GLC_TEXTURE mode are now stored in GL_ALPHA format in order
  to nicely superimpose the glyph on the background instead of rendering it
  over a black box (bug reported by Brandon Casey)
- Fixed all GLC functions that uses individual character : if the current
  string type is GLC_UTF8, the GLint code is now correctly handled
- Fixed a bug in the detection of the filename extension of font files
- Fixed the master creation when glcGenContext() is called : no void master
  should be created anymore
- Fixed a bug so that display lists created by QuesoGLC are now deleted when
  glcDeleteGLObjects() is called or when a master is destroyed
- Strings returned by glcGetc() are now converted into the relevant Unicode
  format
- Added an "uninstall" target to the makefile
- When the shared library is built, the version number is appended to the
  library name and the corresponding links are created when QuesoGLC is
  installed. This allows several different versions of QuesoGLC to coexist
  on most *nix (feature suggested by Pablo Barbáchano).
- Pablo Barbáchano fixed the install process of QuesoGLC

Changes made from the "0.1" release to the "0.2" release:
-----------------------------------------------------------

- Textures in GLC_TEXTURE mode are now of variable size instead of fixed size
  (previously 64x64).It both optimizes the texture memory and removes the
  garbage that could appear when rendering some fonts.
- Added UTF-8 support
- QuesoGLC does not open anymore the font files at font creation. Instead, font
  files are opened when the fonts are added to GLC_CURRENT_FONT_LIST. It lowers
  the number of font files that are simultaneously opened.
- Every strings are now stored internally in Unicode UTF-8 format. Strings are
  converted back to the current GLC_STRING_TYPE "on the fly".
- Get rid of the string list objects (files ostrlst.[ch]) and the Unicode
  character object (files ounichar.[ch]). This simplified the code.
- Now uses standard predefined macros to detect Mac OSX platforms
- QuesoGLC now uses Fontconfig to locate and examine fonts
- Fixed invalid preprocessing tokens of test4 that prevented it to be compiled
  with pedantic-errors enabled.
- QuesoGLC now uses Doxygen for its documentation.

Changes made from the "Birth" release to the "0.1" release:
-----------------------------------------------------------

- Get rid of NDBM : Unicode names are now stored in a const array which is
  automagically built from buildDB.py
- FreeType lists are now used for the string list object, master lists,
  font lists, current font lists and texture object lists.
- A mutex is now used for every access to the database since NDBM is not
  thread-safe.
- Fixed a bug where the content returned by dbm_fetch() was freed. This
  behaviour was wrong since dbm_fetch() returns static data.
- Now uses NDBM (which is much more portable) instead of GDBM
- Fixed a bug in glcDeleteContext() where QuesoGLC tried to destroy the GL
  objects of the current context instead of those of the context to be deleted.
- Contexts are now stored in a linked list and their number is not limited to
  16 anymore.
- Fixed glcGetAllContexts() which returned wrong context IDs and did not zero-
  terminate the array.
- Fixed the error path in __glcInitLibrary where glcCommonArea was freed before
  its members.
- Added many comments to the sources.
- Removed the stupid parameter GLC_INTERNAL_ERROR
- QuesoGLC now computes automatically the resolution of the screen in DPI using
  X window commands.
- The GLC_RESOLUTION parameter now provides a way for the user to choose the
  precision of de Casteljau's algorithm.
- Fixed a bug that occured when a context was deleted : its entry was not
  deleted from the 'stateList' array.
- QuesoGLC now has the ability to use custom memory manager routines
  (see __glcFree, __glcMalloc and __glcRealloc)
- FreeType2 now uses a custom memory manager based on __glcFree, __glcMalloc
  and __glcRealloc. This helps debugging and detection of memory leaks.
- Variables GLC_MIN_MAPPED_CODE, GLC_MAX_MAPPED_CODE, GLC_CHAR_COUNT and the
  list GLC_CHAR_LIST are now updated when a new font file is added to a master.
- Changed license of QuesoGLC to LGPL
- Fixed glcAppendFont() so that it raises GLC_PARAMETER_ERROR if the font is an
  element of GLC_CURENT_FONT_LIST at the beginning of the command execution.
- Fixed glcFont() so that it behaves correctly if the font parameter is zero.
- Fixed glcFontFace() so that it leaves the current face unchanged if it fails
  to set a new face.
- Fixed glcFontMap() so that it checks if the character to be mapped is an
  element of the list GLC_CHAR_LIST.
- Fixed glcFontMap() so that if no character name is given then the code
  'inCode' is removed from the charmap.
- Fixed glcRenderCountedString(), so that it raises GLC_PARAMETER_ERROR if the
  parameter inCount is less than zero.
- Fixed glcReplacementCode() so that it can use a code other than
  GLC_REPLACEMENT_CODE.
- Translated C++ code to pure ANSI C (i.e. get rid of C++)
- QuesoGLC can now be built as a shared library.
