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.
