Mesa's Xlib driver provides an emulation of the GLX interface so that

+<h2>X Visual Selection</h2>
<p>
Mesa supports RGB(A) rendering into almost any X visual type and depth.

-<H2>Double Buffering</H2>
+<h2>Double Buffering</h2>
<p>
Mesa can use either an X Pixmap or XImage as the back color buffer when in
double-buffer mode.

+<h2>Colormaps</h2>
<p>
When using Mesa directly or with GLX, it's up to the application
writer to create a window with an appropriate colormap. The GLUT

+<h2>Gamma Correction</h2>
<p>
To compensate for the nonlinear relationship between pixel values
and displayed intensities, there is a gamma correction feature in

-The progs/demos/gamma.c program may help you to determine reasonable gamma

-displayed in the top row (drawn by dithering) should nearly match those
-in the bottom row (drawn as grays).

This extension adds the glXCopySubBufferMESA() function. It works
like glXSwapBuffers() but only copies a sub-region of the window
instead of the whole window.
