DebugBreakProcess.

- Rewrite the enumeration loop
- Support non-desktop root
- Silence harmless and implemented debug messages

Restored interrupt priorities to correct values.

- optimize FB Locks / Unlocks when RECTs are used

- TRACEing fix

- fix bug in texture upload (I wonder how I missed this :-/ )
- improve the D3D1/2 texture mapping modes

- 24 bpp handling for lock / unlock code
- some better checks for AlphaPixel value
- better TRACEing to better catch threading problems

- only bind textures at start of rendering
- optimized the texture parameter code
- optimize of the 'dirty checking code' for mipmapping
- handles the MAXMIPLEVEL texture parameter

- fix one case of reference counting on textures
- fix stupid bug in texture upload code
- yet another texture enumeration reordering

- use the common code for the FB Unlock code

- some interface changes for future reuse for Blt / Lock code
- fixed some Pitch problems in texture uploads (mostly for 'small'
  mip-mapping levels)

- 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)
