/*
* The Mesa library needs to be able to draw pixels in a number of ways:
* 1. RGB vs Color Index
* 2. as horizontal spans (polygons, images) vs random locations (points,
* lines)
* 3. different color per-pixel or same color for all pixels
*
* Furthermore, the X driver needs to support rendering to 3 possible
* "buffers", usually one, but sometimes two at a time:
* 1. The front buffer as an X window
* 2. The back buffer as a Pixmap
* 3. The back buffer as an XImage
*
* Finally, if the back buffer is an XImage, we can avoid using XPutPixel and
* optimize common cases such as 24-bit and 8-bit modes.
*
* By multiplication, there's at least 48 possible combinations of the above.
*
* Below are implementations of the most commonly used combinations. They are
* accessed through function pointers which get initialized here and are used
* directly from the Mesa library. The 8 function pointers directly correspond
* to the first 3 cases listed above.
*
*
* The function naming convention is:
*
* [put|get]_[mono]_[row|values]_[format]_[pixmap|ximage]
*
* New functions optimized for specific cases can be added without too much
* trouble. An example might be the 24-bit TrueColor mode 8A8R8G8B which is
* found on IBM RS/6000 X servers.
