---------------
- Consolidated v3.0/v2.5 code bases to remove v3.0's beta status

v2.5.02a (6-May-00)
--------
- Win32 - now recognizes VK_APPS (the application menu key)

  clip in the background (looping, if desired)

- Win32 - fixed improper sizing of video frames


v2.5.02 (22-Feb-00)
-------
- Compiler's DefEnum() caused errors on explicit "enumerate globals"
  or "enumerate constants"
- BeOS - Added character-encoding selection option and full-screen mode
- In Kent's ports, a mouse-click now passes keycode=1 to
  hugo_keywaiting(); also sets display.cursor_column and
  display.cursor_row
- Also in Kent's ports, fixed hugo_getline() so that it doesn't
  call hugo_scrollwindowup() unless we're at the window bottom
- Glk - Half-fixed hugo_settextpos putting things off-screen with
  positioning based on display.screenheight and screenwidth
- Removed usage of global 'z' from both heheader.h and hcheader.h
  (meaning a fairly thorough rewrite of some sections)

- Added better compile-time checking to property value syntax
- Occasional usage of a local __selectvar in compiling select-case
  for proper working of random(), ++, etc.

- Win32 - Context menus now track either mouse button
- "text to <array>" printing now always appends a terminating zero
  (without advancing the textto index)
- Win32 - v2.5 now uses old non-DirectSound audio; v3.0 currently and
  inexplicably needs a debug-built libmik.lib to overcome hissy
  DirectSound playback

--------
(Released only for the Win32 package of Guilty Bastards)

  proper processing

  dialogs were displaying only directories

  music.raw file dumps when the sound device is unavailable
