screen (see exmipmaps) - now set explicitly.
- [OSX Driver] Mouse setup not correct w.r.t hardware cursor (see recent

mipmaps. Credit to 'Mutator' for helping in debugging.
- [Texture] Workaround for crash on Matrox G200 cards. gluBuidl2DMipmaps
doesn't seem to be affected, so we're using that; up-converting

prevent the window to be resized (issue reported by Benny Kramek).

the screen bitmap.
- [X Driver] Fixed a bug that made AGL crash when trying to switch several
times between the Allegro's DGA2 driver and the AGL's OpenGL driver
(thanks to Chris Martens for pointing out the fix).

is now disabled for consistency with the behaviour of the same function
when mipmapping is enabled (issue reported by Steve Apostol).

and did not set them back to their previous values when switching back

* Peter Hull
- [AGLF] Fixed a bug in fontconv.c where texture sizes were sorted before
they were set up.

reported by Martin Dusek.
* Robert J Ohannessian
- [Allegro driver] Fixed video bitmap creation code for bitmaps that
have a dimension that is a multiple of 256.
- [Build] Fixed warning with -mpentium on DJGPP and Mingw. Now
using -mcpu=i586.

(Some drivers seem not to like upside-down rectangles).
- [Ext] Fixed a bug where AGL claimed in the log file that it both failed and
succeeded to load an extension (actually AGL failed).
- [Core] Fixed a bug where OpenGL strings returned as NULL caused
"allegro_gl_is_extension_supported" to crash (issue reported with Mesa).

resolution so that fullscreen-only drivers do not crash anymore.
- [Core] Made AllegroGL to default the OpenGL version to 1.0 when the drivers
do not return any version info.
* Igor Gnip

arbitrary depth to the screen and video bitmaps.

to GLsdk if the user puts it in the add-on directory.
This allows usage of GL 1.3 and extensions under Windows
and Linux.
- [Core] Made double buffering, and hardware acceleration default
settings. You don't need to specify those any longer unless
you want to require them.
- [Windows Driver] Bug fix in the Windows full screen color depth
detection code.
(thanks to George Foot for pointing it out)
- [Docs] Various documentation updates
- [AGLF] Fixed a bug in the system fonts in AGLF. A float was
accidentally type changed to an int.
- [Examples] Fixed yaw/pitch/roll in excamera.c. Thanks to George
Foot for the correct equations!
- [Math] Fixed a bug in excamera.c and maths.c which caused glRotate
to rotate around a zero vector.
- [Allegro Driver] Text partially off screen renders correctly now.
- [Scorer] Added RGBA accumulator depth
- [Core] Added extra checks to make sure the user doesn't call
GL commands without a valid context.
* Hein Zelle
- [Build] Changed the schell script of utod and dtou so that they can work
on more platforms (Irix comes to mind).
* Bertrand Coconnier
- [Allegro Driver] Added sub-bitmap support for the screen
- [Ext] Added GLsdk integration to the Unix build process.
- [X Driver] Fixed a bug that prevented the Packed Pixels extension to be
correctly handled.

- [Core] Added 'allegro_gl_error' variable in order to complete usual allegro
error messages
- [Core] Added 'allegro_gl_set/unset_allegro_mode' functions. These functions
should now replace the 'allegro_gl_set/unset_projection' pair (which have
been kept for backward compatibility).
* George Foot
- [GUI] Added GUI manager routines
- [Build] Updated the MSVC build batch files to include gui.c and exgui.c
- [GUI] Made the mouse cursor hide when the pointer is outside the window
* Nick Sumner

Changes from 0.0.24 to 0.1.0:
-----------------------------
Note: AllegroGL 0.1.0 is NOT source compatible with AllegroGL 0.0.24
* Bertrand Coconnier:
- Changed the DOS port into a generic driver that can either be built on DOS
or Unix platforms (thanks to Allegro and Mesa portability !).
- Upgraded the DOS (aka generic) driver to Mesa 4.0 (splitted amesa.c into
amesa.c and raster.c)
- allegro_gl_get_proc_address now works for the DOS (aka generic) driver too.
- Added automatic dependencies generation for the Unix build.
- Fixed the draw_glyph method of the generic driver.
- Fixed the DJGPP makefile (according to Bob's new makefile system).
- Fixed the color conversion problem of the generic driver (RGB components
were sometimes mixed up)
- Fixed a bug in the glClear method of the generic driver : it now takes
glClearColor into account.
- Fixed a bug that made the generic driver overwrite Allegro's vtables, thus
rendering Allegro graphic functions useless.
- Fixed a bug in 'remove_allegro_gl' : Allegro's gfx drivers are now correctly
restored .
- In alleggl.h, the prototypes of the functions that manage OpenGL extensions
are now included in 'extern "C"' : they can now be used in a C++ prog.
- Added an example (exgui.c) of how to use Allegro GUI routines within
AllegroGL
- Fixed a tiny bug in (and BTW simplified) the clear_to_color method.
* Robert J Ohannessian:
- Updated the Mingw compilation instructions.
- Updated makefile system to be more consistent with itself and with
Allegro's. MSVC and Mingw are done. Unix and DJGPP are pending.
- Fixed a bug in allegro_gl_printf() that caused it to not restore
the texture binding in some circumstances.
- Documented strange behaviour of OpenGL - the default texture is not 0
if you use glGetIntegerv(GL_TEXTURE_2D_BINDING).
- Added a new example/tutorial to show how to use a camera with
quaternions in OpenGL.
- Removed ability to draw AllegroGL fonts using Allegro functions.
Use AGL functions for AGL fonts, and AL functions for AL fonts.
- Glyphs are now sorted and fitted to textures. This should reduce wasted
texture space, and fix some problems on Voodoos (but not all).
- AllegroGL now *requires* Allegro 4.0.0.
- Fixed most compilation warnings.
- Cleaned up conversion code, and split aglf.c to fontconv.c
- Reduced memory used by converted font.
- Blank space in glyphs is now cropped to save more texture space.
The example programs should now work on the Voodoos.
- Font conversion code now takes a scaling factor (see docs for details).
Use 16.0 so fonts get generated as in 0.0.24-.
- Slight tweak in the alpha font converter so that end value range is
[0..255] and not [0..254].
- Added ability to save/load current configuration.
- Made set_color_depth be respected by AllegroGL, but only if the other
AllegroGL functions weren't being used.
* George Foot:
- Fixed the Unix makefile
- Added the capability of having glyphs placed arbitrarily in a texture.
* Julien Cugniere:
- Fixed a bug in allegro_gl_screen_triangle so that 2D triangles are not drawn
twice anymore.
* Igor Gnip:
- Added the STATICLINK option for Mingw and MSVC compilers

- Added an experimental scorer to the DOS port
- The Read and Draw buffers are now handled by two different pointers on the
DOS port.

- Fixed blitting to the screen from a < 24bpp bitmap in Windows.
- Fixed a crashing bug when AGL wasn't able to properly set up a mode.
- Added extra debug info to the Windows driver

* Robert J Ohannessian
- Fixed error in texture uploading code.

vline/hline/line/rectfill and video->screen blits are supported.
(need latest CVS of Allegro, or 3.9.38).
- Fixed the 2D projection matrix to work with exact coordinates (according
to the red book anyway)
- Fixed a bug that made AllegroGL crash when doing screen->memory blits.
* Bertrand Coconnier
- Removed the -g switch for the Unix optimized build
- Fixed a bug that generates a segmentation fault when
the app switches between fullscreen and windowed mode
in X.
- The X fullscreen functions have been merged with the
windowed ones (it allows to share much code between the
two drivers)
- Mouse should work under fullscreen in X.
- X Fullscreen driver should also cleanly quit.
- Cosmetic changes in the X code (ustrzcpy, h/w acceleration detection,
extra debug info)
* George Foot

properly work in alternate color depths (thanks to stoney``,
_deserel and networm, from #allegro on EFNet for the bug reports!)

- Renamed the LOG macro to AGL_LOG to avoid conflicts.
- Added a compile-time version check for Allegro.
- Added a compile-time version check for OpenGL 1.1

allegro_gl_bitmap_color_format() and allegro_gl_bitmap_type())
- Fixed the color bug in extext
- Merged the texturing code from AGLF and AllegroGL
- Added a new option for mipmapping.

Changes from 0.0.10 to 0.0.12:
------------------------------
