Changes from XPaint 2.5.9 to XPaint 2.6.0
- merged a patch from Greg Roelofs fixing PNG read & write
code for recent versions of the PNG library;
older readPNG.c and writePNG.c combined into readWritePNG.c
Changes from XPaint 2.5.8 to XPaint 2.5.9
- snapshot.c: Introduced new "Snapshot" operation (grabbing a
window or mouse-selected rectangle from screen)
- Help.txt: updated Help file accordingly
Changes from XPaint 2.5.7 to XPaint 2.5.8
- operation.c: Reorganized order of icons in main control panel
- graphic.c: Introduced a "Clone region" function
- graphic.c: Added a "Print" option in the file menu, to the effect
of calling an external printing utility (xv is a good candidate)
- splineOP.c: Created basic spline curve operation
- rw/writeTIFF.c: Bug fix; writing TIFF was broken for depth > 8.
Changes from XPaint 2.5.6 to XPaint 2.5.7
- Help.txt, README: Fixed addresses.
Changes from XPaint 2.5.5 to XPaint 2.5.6
- Imakefile: Undid change made to support OS/2 that used the
LibraryTargetName() macro. Now use linker path to achieve the
same. Suggested by John Breslin <breslin@cadence.com>.
- iprocess.c: Change by James G. Feeney <james@albion.nurealm.net>:
I suggest that a more useful edge extension to use in the
smoothing function would be the original image reflected at
the edges for the edge extensions, and the original image
reflected at the corners for the corner extensions.
This approach still allows "smoothing" with smoothing
distances larger than the original image size (a long but
narrow canvas maybe?), since the extended image would simply
be the reflection and then the re-reflection.
This approach simply assumes that the "smoothing" source-image
is a reflective-tiled version of the original image.
This reflective-tiling approach avoids the artifacts and
subsequent problems mentioned, is easy to visualize, and
produces predictable results. Furthermore, I believe this
approach is appropriate for _all_ the effects generated by
convolution.
Changes from XPaint 2.5.4 to XPaint 2.5.5
- fillOp.c: press(): Free allocated memory as suggested by Richard
Hirst <richard@sleepie.demon.co.uk>.
- main.c: The 'visual' patch introduced in 2.5.1 assumed that there
was never more than 5 arguments on the command line. Fixed. Reported
by Mirsad Todorovac <mtodorov@grf.hr>.
- Various changes for glibc.
Changes from XPaint 2.5.3 to XPaint 2.5.4
- CygWin32 portability patches from Arlindo da Silva
<arlindo@niteroi.gsfc.nasa.gov>.
- FreeBSD portability fixes from Justin M. Seger
<jseger@freebsd.scds.com>.
- Several patches submitted by Andreas Czechanowski
<andreas@inspc44b.ins.uni-stuttgart.de>:
- brushOp.c: Transparent brush now ensures to reach the "final"
color when painting over at one place long enough. There was a
roundoff problem when converting float to integer.
- chroma.c: The "select color range" dialog had been bound to the
Canvas from where it was opened the first time. When another
Canvas was opened and the first one was closed, calling "select
color range" from the new Canvas caused a crash.
- iprocess.c:
1) The convolution routine for the image filters has been speeded
up: The sum of all matrix elements only has to be computed
once, not while processing every pixel.
2) Inverting an image crashed, at least on my 24bpp-display.
Changes from XPaint 2.5.2 to XPaint 2.5.3

images where width and/or height is less than the dimensions of the
brush. Reported by Paco Hope <bah6f@cs.virginia.edu>.

what you expect.
- Local.config: Don't hardcode CDEBUGFLAGS. Reported by Mikhail
Teterin <mi@aldan.ziplink.net>.

brush (only works well on TrueColor visuals).
Brush cursor is the correct size when zooming.

Snap rounds instead of truncating (#define TRUNC_SNAP if you want the
old behaviour).
1.4 Changed region functions:
Holding Shift down while moving a region constrains movement to
horizontal or vertical.
Holding Shift down while rotating a region constrains rotation to
multiples of 15 degrees.
1.5 New region functions:
'Crop to Region' tool.
Cursor keys can be used to move region in 1 pixel steps.

know.
'Region' menu split into 'Region' and 'Filter' menus, the latter for
image processing functions.
Busy cursor while saving.
2 Fixed bugs:
Changing the image size no longer does funny things
to the fatbits cursor.
Changing the zoom on the canvas now resizes and
repositions the fatbits cursor.
