- * 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.
