- cleaned-up the GL / device critical section handling

- no need anymore to flush to FB on execute buffer calling

- fix compilation on non-recent glext.h systems

  surface.c/*texture.c (with add of lockable, locked and Dirty flags)
- add of dirtyRect/dirtyBox for better dirtification management (not
  used yet, but huge optimisation can be possible now)
- fix some debug traces (well it's better to use debug_d3dpool)
- fix some stupid regression on point parameters (forgot to check
  extension on fillcaps)

  defines and the caps defines
- cleanup of device.c using the caps defines (avoid the #ifdef
  nigthmare)
- add {Set,Get}GammaRamp support

- split of CreateDevice gl/gxl detection code into FillGLCaps
- implementation of resolution change (using ChangeDisplaySettings)
  but desactived as ChangeDisplaySettings don't seem to work well
- begin of swap chain support (now need to split/clean
  gxlpbuffer/glxpixmap code for swap chain use)

saved snapshot correctly.

  ActiveRender)
- fix stupid rescaling of colors values on SaveSnapshot

- pixel shader code split into a new "COM object" (as done before for
  vertex shader)
- some fixes on Validate* functions call types
- add pixel shader (ie fragment_program) detection on caps code

utils module, and clean up the main code path.

- more cubetextures fixes (now d3d8 sdk cubemap sample work almost
  perfectly)
- add a new debug function "debug_d3dpool" and use it
- add a new param (the device) for the conversions functions (because
  we need to check caps to see how to convert)
- some crashes fixed in render to surface code with no stencil-depth
  surface
- a very simple cliplane fix
- a stupid palettes fix (stupid language)
- begin of anisotropic filter support
- begin of compressed textures support
- a very useful debug functions: IDirect3DSurface8Impl_SaveSnapshot to
  dump surfaces as png ;)
- many useful surfaces debug code (using SaveSnapshot)

GL_EXT_stencil_wrap extension).

  using glx pbuffers (with a useful debug code to display rendered
  surface into window drawable)
- better cubetextures
- split utilities functions into utils.c and added more
- more readable debug again
- a better caps code (not perfect but i'll use glx code later)
- use of the new caps code
- begin of UpdateTexture
- begin of Cursor support
- cleaning most of deprecated #if 0/#endif
- correct some lockable/unlockable behavior
- correct some returns code

  MIPMAP flag set
- add GL crit. section support for matrix setting
- support the various BLEND texture operations

and return that no palette entries had to change.

Migrate int21 set drive routine to winedos.

order to better support SCSI drives.

console size. Cursor is no longer left into wrong location after
screen updates.

- made the decompression code a bit more pedantic to avoid crashes
- fixed startup without .HLP filename passed on command line
- passed a few more commands from remote applications to the macros
