+ * 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.
