00026 //       Class : OsMesaGraphicsPipe
00027 // Description : This graphics pipe represents the interface for
00028 //               rendering with direct calls to the Mesa open-source
00029 //               software-only implementation of OpenGL.
00030 //
00031 //               Raw Mesa supports only offscreen buffers, but it's
00032 //               possible to create and render into these offscreen
00033 //               buffers without having any X server or other
00034 //               operating system infrastructure in place.
