-<p>
-Mesa supports the following environment variables:
-</p>
-<ul>
-<li>MESA_NO_ASM - if set, disables all assembly language optimizations
-<li>MESA_NO_MMX - if set, disables Intel MMX optimizations
-<li>MESA_NO_3DNOW - if set, disables AMD 3DNow! optimizations
-<li>MESA_NO_SSE - if set, disables Intel SSE optimizations
-<li>MESA_DEBUG - if set, error messages are printed to stderr.
-If the value of MESA_DEBUG is "FP" floating point arithmetic errors will
-generate exceptions.
-<li>MESA_NO_DITHER - if set, disables dithering, overriding glEnable(GL_DITHER)
-</ul>
-
-<p>
-The following environment variables are only applicable to the Xlib/X11
-software driver:
-</p>
-<ul>
-<li>MESA_RGB_VISUAL - specifies the X visual and depth for RGB mode (X only)
-<li>MESA_CI_VISUAL - specifies the X visual and depth for CI mode (X only)
-<li>MESA_BACK_BUFFER - specifies how to implement the back color buffer (X only)
-<li>MESA_GAMMA - gamma correction coefficients (X only)
-<li>MESA_XSYNC - enable synchronous X behavior (for X debugging only)
-<li>MESA_GLX_FORCE_CI - if set, force GLX to treak 8bpp visuals as CI visuals
-<li>MESA_GLX_FX - set to either "fullscreen" for full-screen rendering,
- "window" to render into a window, or "disable" to disable the Glide driver.
-<li>MESA_GLX_FORCE_ALPHA - if set, forces RGB windows to have an alpha channel.
-<li>MESA_GLX_DEPTH_BITS - specifies default number of bits for depth buffer.
-</ul>
