I have implemented the above api for the opengl, x11, directfb and
software renderers. I have also renamed *TEXTUREBLENDMODE* constants to
BLENDMODE*. The unix build compiles. The windows renderer still needs to
be updated, but I have no windows development machine at hand. Have a
look at the x11 renderer for a sample.
Vector games now run at 90% both on opengl and directfb in comparison to
sdlmame's own opengl renderer. The same applies to raster games.
The diff also includes
a) Changed XDrawRect to XFillRect in x11 renderer
b) A number of changes to fix blending and modulation issues in the
directfb renderer.

working earlier this week.
I added some more trace code to SDL_x11events.c
In SDL_X11opengl.c I modified SDL_GL_GetSwapInterval() so that it returns a pretty good value even if you have the SGI swap extension instead of the MESA swap
extension. I just saved the value you set and return it too you.
following event can reset done to 1 and prevent the program from terminating when told to. I fixed the while loop that handles events to check for the state of done
after handling each event. That could leave some events unhandled when the program exits, but it ensures that the program will exit.

Subject: SDL 1.3 keyboard plan
After lots of discussion with Christian, this is what we came up with:
> So, to sum up...
> SDLK_* become the physical keys, starting at > (1<<21)
> We create a macro SDLK_INDEX(X)
> We have two functions SDL_GetLayoutKey(SDLKey) and SDL_GetKeyName()
> SDL_GetLayoutKey maps to UCS4 for printable characters, and SDLK* for
non-printable characters
> and does so based on the OS's current keyboard layout
> SDL_GetKeyName() handles both SDLK_* and UCS4, converting UCS4 to UTF-8 and
converting SDLK_* into our names, which are UTF-8 for printable characters.
> WASD folks use SDLK_*, and 'I' folks use SDL_GetLayoutKey(SDLK_*)
Here is the patch he came up with, and his e-mail about it:

Here goes! Thanks for having a look. Don't hesitate to comment if
anything does not conform to your ideas.
One caveat: Committing this now may break compilability of some video
drivers - specifically, if they use any of the SDLK_* codes that were
obsoleted and moved into SDL_compat.h. I only tried Cocoa (which did
break, but is already fixed) and X11 (which didn't, but then its key
handling is #iffed out). If that's a problem, it may need to go into
a branch.
