Subject: 32 & 16 bit versions of blendrect and blendline
attached are 32, 16 and 15 bit versions of the blendrect and blendline
functionality. There was an issue with the bresenham alg. in drawline
which I also fixed.

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.

FIXME: this is a memory leak. We don't have an SDL_FreeAudioCVT() yet.

The API specifies that SDL_OpenAudio() will fill out the 'desired' audio spec
with the correct samples and size set by the driver. This value is important
since it may be used by applications that size audio buffers, etc.
However, we want to allow advanced applications to call SDL_OpenAudioDevice()
which gets passed a const 'desired' parameter, and have the correct data filled
into the 'obtained' parameter, possibly allowing or not allowing format changes.
So... 'obtained' becomes the audio format the user callback is expected to use,
and we add flags to allow the application to specify which format changes are
allowed.
Note: We really need to add a way to query the 'obtained' audio spec.

Subject: SDL: Mouse last_x, last_y into SDL_Mouse
the attached diff moves the static vars last_x and last_y into
SDL_Mouse. These, as far as I understand it, should be tied to the
individual mouse.
The patch also makes the code check for out of window conditions of
mouse->x,y when relative movements are passed to MouseSendMotion.
Also attached is the latest DirectFB code (dfb20081208) supporting
multiple mice and keyboards. This works quite well with sdlmame now. It
however needs more testing with different directfb configurations.
