  20/March/2000 GLMame32 Version 36rc2 OpenGL-Display-AddOn 1.3beta
  ==================================================================

  General Changes

	o Taken Windows-Source-Base from Mame32-36b16 !

	o Taken MAME Source Mame 36rc2 !

  Mame32 integration

	o Now GLMame32 just adds the OpenGL display driver !

	o Vector Games are support for OpenGL only in this Version !

	o the '#define xgl' exists everywhere in the source,
	  except of the Ressource Files :-(

  OpenGL Changes

	o Because of the lower changes, 
          the performance should be increased ...

	o Now useing normal coordinates [0.0-1.0].

	o The vector implementation is bug-fixed,
          and is able to show the bitmap for options etc.
	  The artwork bitmap still does not work ... but is coming !
	  The Fullscreen mode for vectors has the correct aspect-ration now !

	o The color allocation is bug-fixed,
          so the "disclaimer" where you have to say OK the first time
	  is viewabel !
	  Also the color sheme should accept high color games now ...


  15/June/1999 GLMame32 Version 35rc1 OpenGL-Display-AddOn 1.2
  ============================================================

  General Changes

	o Taken Windows-Source-Base from Mame32-35b13 !

	o Taken MAME Source Mame 35rc1

  Mame32 integration

	o Now GLMame32 is compiled with MSVC 6.0

	o Now GLMame32 just adds the OpenGL display driver,
	  - the others are still avaiable !
	  - you can choose OpenGL within the properties.advanced dialog-box.

	o The following values are transparent to the main Mame32
	  and are saved into the config-file:
		alpha, gamma, OpenGL-Usage, automatic-fps, skip-fps,
		fullscreen

	o osd_pause is implemented

	o the auto-pause mechanism has changed a bit (implementation).

	o the '#define xgl' exists sometimes in the source,
          but in a way of hurry - it is not used consitency.

	o the opengl-part supports png-files, but just the
	  poor mame-bitmap quality :-( yet !

  OpenGL Changes

	o getting PIXELFORMAT with depth 16 bits as default

	o IF alphablending == FALSE
		- Only RGB rendering is done, the Alpha-Channel is dropped !
		- Alpha will modify the RGB intensity !

	o The maximal texture-size is tested and used,
	  so the bitmap may be displayed within more than one
	  texture.
	  This is a must for OpenGL hardware with a restricted texture size !
	  The texture-size of each testure is equal, but only the 
	  viewable part is watchable.
	  The width and height is tested in a way, 
	  so they can be different.
	  The test algorythm tests till the texture-proxy allows
	  the settings :-)

	o The maximal texture width and height can be forced to a spec. value !
	  Of course the used value is adapted to 2**n=size :-) !

	o the opengl-part supports png-files, but just the
	  poor mame-bitmap quality :-( yet !

	o while setting properties.misc.error_log to true, 
	  you can read the file 'glmame32_stderr.log' for information
	  about some opengl-metrics and the opengl-vendor !
	  The log file catches the info of the last game-run !


  15/May/1999 GLMame32 Version 35b12 OpenGL-Display-Only 1.1
  ===========================================================

	o Using the original bitmap in ONE texture-buffer !
		- So the *_create_display and *_new_bitmap is patched !
		- Using the true view size, to update the texture

	o if the EXT functions is not their, the other one works !
	  - The non EXT function for Color-Index works,
		but - of course - it is _very_ slow !
	  - The non EXT function for color index can be used,
		while toggeling the flag in the GL-status dialog.
		Be aware of broken OpenGL drivers ...
		... the ELSA driver for Gloria L/MX frozes my NT-machine :-(,
		so i use 3DLabs now (faster for Quake2 anyway ...).
	  - The non EXT support works only from this version on !

	o Using the true color number for the palette

	o Using the right component size of the bitmap

	o using the alpha values for brightness

	o added win32 function to load the EXT functions !

	o added snapshot support for:
		- BMP (Win32 only)
		- PPM (Win32 and all the others - now it works :)
		- JPG (why not - but the quality is poor ..)
