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.
     2 1.3 release checklist:
     3  * Add higher precision timers for profiling
     4  * Implement YUV texture support
     5    - in progress, software support is done, Ryan is working on OpenGL shaders
     6  * Implement desktop video mode change notification?
     7  * Implement icon support (with translucency?)
     8  * Add draw blend mode and line drawing support for software renderer and win32
     9  * Verify mouse grab support
    10  * Properly handle mouse grab with Vista DPI scaling
    11  * Make sure the mouse is where it's supposed to be when un-grabbed
    12  * Test native window codepath
    13  * Add keyboard enumeration / name query API
    15 Wish list for the 1.3 development branch:
    18  * Add a way to register custom events
    19  * DirectInput joystick support needs to be implemented
    20  * Explicit vertical retrace wait (maybe separate from SDL_Flip?)
    21  * Shaped windows, windows without borders
    22  * Multiple display support
    23  * Add a timestamp to events
    24  * Add audio input API
    25  * Add modifier state to key and button events
    27 In the jump from 1.2 to 1.3, we should change the SDL_Rect members to
    28 int and evaluate all the rest of the datatypes.  This is the only place
    29 we should do it though, since the 1.2 series should not break binary
    30 compatibility in this way.
    32 Requests:
    33  * PCM and CDROM volume control (deprecated, but possible)
