  directory) - automatically reload on startup
  OK - 7/4/97

* Warn if exiting/opening/clearing/newing and changes to buffer
  OK - 19/4/97

* Do I want all windows closed upon DSP operation then opened
  again once DSP has finished ? (preference = auto DSP close)
  OK - 19/4/97

* Load in samples given in command line (after DAP)
  OK - 8/5/97

* Desk (8 channel) mix play - allow choosing of samples
  OK - 8/5/97

* No changes to audio globals on start-up/load/create/select/exit
  (preference = auto global adjust)
  OK - 8/5/97

* Save copyright chunk ? (preference = sox compatibility mode)
  OK - 8/5/97

* Edit forms which depend on range / duration - update if range
  changes and re-check range valid and non-zero when click OK
  OK - 12/5/97

* Linux conversion for AudioFile library
  OK - 1/6/97

* Linux conversion for Audio Library
  OK - 1/6/97

* Run Shell command (one buffer/all buffers/stored macros/load/
  save as with preferences)
  OK - 21/6/97

* More checks on text input (ignore blanks)
  OK - 22/7/97

* Adjust DC working correctly on stereo and quadro samples
  OK - 22/7/97

* Macros working correctly (text, raw, temp and AIFF)
  OK - 22/7/97

* When adjusting ranges/loops centre around mouse position
  (adjust for "middle")
  OK - 22/7/97

* Sorted out resize on suitable forms (gravities and show mode)
  OK - 22/7/97

* Go through all forms - remove excess button bordering and
  reduce form size where possible
  OK - 22/7/97

* Reduce borders and minimum size on main form
  OK - 22/7/97

* All forms must be visible on 640 x 480 screen (except pitch
  form as the keyboard is long)
  OK - 22/7/97

* Wait cursor should appear on all forms - not just main form
  OK - 22/7/97

* Add new edit menu item - "remove" - same as copy then a zero
  OK - 22/7/97

* "Single" edit mode - range marking - selects track depending
  where you push the mouse (preference = auto edit mode)
  OK - 22/7/97

* Put in idle delta value of 500ms (preference for time)
  + remove idle delta (zero) when record levels on or keyboard
    pitch select on
  + put back to 500ms when record levels off or keyboard pitch
    select off
  + put up to 2000ms (preference for time) when intense
    processing (time stretching or DSP)
  + put back to 500ms when time stretch or DSP finished
  OK - 22/7/97

* Ramp form - can ramp balance (must be stereo/quadro) as well
  as amplitude (NB chan 1/2 select for quadro)
  OK - 22/7/97

* Sample display - quick or accurate. Quick is as now - one
  sample per pixel. Accurate calculates maximum and minimum
  sample for each pixel)
  OK - 22/7/97

* Sort out "_ALerror: code=12 ALgetdefault: invalid audio device
  parameter: 15/17" on some SGs - don't attempt ALgetdefault if
  first time fails
  OK - 22/7/97

* Range select mode - normal/alternative. Normal is as now -
  but right button grabs and drags range start / end - whichever
  is nearest. Alternative is left button to grab / drag range
  start, right button is range end.
  OK - 22/7/97

* Range crossover mode - on/off. Affects crossover ability when 
  dragging ranges and adjusting range with range form buttons and 
  textual inputs. If set on, will drag both start and end
  forwards or backwards with buttons and textual inputs (length
  stays at zero). Normal left button drag will always crossover
  - on normal mode only affects right button drag.
  OK - 22/7/97

* DSP execute - time remaining dodgy - check the way it is
  calculated and make more stable (eg can't increase by less than
  5 seconds)
  OK - 10/8/97

* Window titles for convert forms are too wide for actual forms
  OK - 10/8/97

* Take out register variables in resampling - can cause problems
  OK - 11/8/97

* Sample rate selector is too wide on play, record, post and mix
  play forms - make it smaller
  OK - 12/8/97

* Accurate line draw - need to draw extra line between previous
  min/max and current max/min if not overlapping (to give
  continuous line)
  OK - 13/8/97

* Performing undo/redo maintains edit mode
  OK - 27/9/97

* Added button bar with new and open buttons and key shortcuts
  OK - 27/9/97

* Added save, cut, copy and paste buttons
  OK - 14/10/97

* Added shortcuts for existing buttons and updated menu entries
  OK - 14/10/97

* Macro - when in single channel mode, with pipe or raw and a
  single channel range selected now saves out and reloads
  correctly (deals just with the channel selected)
  OK - 14/10/97

* Executing macros (with pipe or raw) now maintains loop
  positioning
  OK - 14/10/97

* Complete overhaul of directory structure and makefiles - note
  all architectures now use gcc/g++
  OK - 14/10/97

* Linux audio stuff (DPTich_linux_audio, DPTich_linux_audiofile,
  DPTich_linux_ieee, DPTich_linux_macros) converted to C (rather
  than C++) so that they are easier for other people to use !!
  OK - 15/10/97

* Revamped Sun compile to use OSS and XPM directories as I don't
  have root password on the Sun at work !!
  OK - 25/11/97

* Added raw event handler on main form which looks out for
  keyboard shortcuts with no appropriate button (eg CTRL-Q quits
  the program)
  OK - 25/11/97

* Added shortcuts to most "dialog" forms - CTRL-O is OK and
  CTRL-C is cancel.
  OK - 4/12/97

* Added preference for input text size (FL_TINY or FL_SMALL) -
  appropriate text boxes also affected.
  OK - 4/12/97

* Fixed bug in linux audio library - wrong size for array - could
  lead to seg faults :((
  OK - 21/12/97

* Added cool zoom slider with snazzy buttons onto zoom form -
  makes quick zooming in and out a breeze !!
  OK - 22/12/97

* Added vertical zoom and scroll controls for vertical detail
  OK - 22/12/97

* Tidied up forms - particularly resizing problems
  OK - 6/1/98

* Moved normal zoom slider onto the main form for easier access
  OK - 6/1/98

* Sorted out macros to work slightly more intuitively when
  deleting and adding macros.
  OK - 8/1/98

* Added new macro mode so that mutiple channel macro runs may be
  run as interleaved single outputs (as before) or separate macro
  runs for each channel. This allows single channel macros to be
  applied to each channel individually !! (thanks to Amrose Field
  for the suggestion).
  OK - 8/1/98

* Improved macro feature such that multiple macro output windows
  may be created and displayed.
  OK - 8/1/98

* Fixed bug in drawing routine for sample - taking log10 of zero
  causes problems on some architectures :( (Linux Alpha is one of
  them !!).
  OK - 26/1/98

* Fixed bug when quitting time stretch resampling - could cause
  multiple do_forms calls which then never quit - simple locking
  to solve. Also means heavy/normal idle back in for
  resampling :)
  OK - 26/1/98

* Added makefiles for Linux Alpha (same as Linux but not Big
  Endian)
  OK - 15/2/98

* Fixed bug - normal/heavy idle time preferences were not being
  updated from the preferences form correctly
  OK - 28/6/98

* Added a wrapper around fl_get_input calls (fl_safe_get_input)
  which can never return NULL. This is because it was always
  assumed that fl_get_input didn't return a NULL but actually
  it can sometimes
  OK - 28/6/98

* Added a border width preference so the user can change the
  border width of all xforms objects used in DAP
  OK - 28/6/98

* Fixed a bug in the linux audiofile source code - AFseekframe
  wasn't taking the number of channels into account
  OK - 28/6/98

* Slightly better handling of which directory preferences and
  macros are saved in - more likely to use $HOME now which is
  much better than using "."
  OK - 28/6/98

* Improved time-stretch resampling for high quaity setting
  OK - 7/11/98

* Reorganised entire project structure to have libaudio and
  libaudiofile in separate build directories
  OK - 7/11/98

* Took out nearly all references to "long" and replaced with
  "int" so the Linux/Alpha compile should work better
  OK - 7/11/98

* Added ability to select endian-ness of raw data when using
  macros
  OK - 16/11/98

* Added ability to import and export RAW samples to and from DAP.
  The selection of data format, signed-ness, endian-ness and
  number of channels (import only) are selectable by the user.
  The data formats are the same as those provided by the raw
  data macro facilities.
  OK - 18/11/98

* Improved closing of audio ports on Linux by using the new Linux
  only Audio Library call, ALflushport, to output the current
  sample buffer immediately. This stops the annoying "sample
  stopped playing too early" that used to happen - particularly
  noticable with short one-shot samples.
  OK - 18/11/98

* Improved the code in DAP to allow "all warnings" compiles - ie
  you can compile with -Wall in gcc and get no warnings. The
  majority of changes were removing unused parameters and
  variables.
  OK - 12/12/98

* Improved the use of file selectors within DAP. Now the same file
  selector is always used so the "current" directory is always the
  last directory you loaded from or saved to. The code for file
  selection was tidied up as well.
  OK - 12/12/98

* Added the ability to import and export WAV files to and from DAP
  OK - 14/12/98

* Improved makefiles - better include for /usr/X11R6 and the sound
  directory test program (SampleTest) builds with no reference to
  xforms or X11 stuff.
  OK - 10/1/99

* Added makefiles and modifications for building under NetBSD
  (thanks to Berndt Josef Wulf for providing these)
  OK - 11/11/99

* Updated documentation and added versioning to DAP starting with
  version 2.1. Also removed redundant revision and date from all
  source code files
  OK - 20/02/00

* Added ability for libaudio to take in devices for dsp and mixer
  OK - 20/02/00

* Sox now has all string handling broken for miscellaneous string
  (it cannot handle odd lengths - pad byte isn't handled) so
  "Sox Compatibility" now save no miscellaneous strings at all
  OK - 20/02/00

* Fixed potential bug with record channel switches
  OK - 23/02/00

* Changed libaudiofile to use system buffered IO (using FILE *
  pointers) rather than raw unbuffered IO (using integer file
  descriptors) to give increased loading and saving times
  OK - 28/02/00

* Added ability to specify audio and mixer devices in preferences
  OK - 29/02/00

* Merged in NetBSD patches for makefiles and standard audio device
  OK - 29/02/00

* Added ability to balance / pan in mixplay screens (2, 4, desk)
  OK - 07/03/00

* Added FEATURES document
  OK - 07/11/00

* Update TODO document with user suggestions
  OK - 07/11/00

* Remove Linux signal workaround (does not appear to be needed any
  more but have left the code in place)
  OK - 07/11/00

* Fixed up a small bug in the WAV export routines (chunk size of
  the "cue" chunk was wrong)
  OK - 03/10/01

* Fixed up a bug which meant while recording (either actual
  recording or calibration) you could attempt to record the
  display, calibrate, or switch on the level meters. This
  would cause DAP to lock /dev/dsp and crash out. Now these
  buttons are disabled during any record process.
  OK - 03/10/01

* Fixed up build so that the location of XForms is always grabbed
  from the XFORMS environment variable rather than being defined
  explicitly in all of the makefiles.
  OK - 04/07/02

* Added play (sample, display, range), stop, release, select all
  buttons in main toolbar (all with shortcuts). Also added
  shortcuts for zoom in/out/all, scroll left/right/fast/slow
  and being/end.
  OK - 08/07/02

* Fixed up reading of textfields on range, display and loop
  screens so that empty strings do nothing (caused problems
  when hiding the forms as the strings got read and things
  got set).
  OK - 08/07/02

* SG makefiles now use CC by default and added another ignored
  warning for this platform.
  OK - 08/07/02
