silent, flush, incomplete_tex and incomplete_fbo flags were not
documented (see src/mesa/main.debug.c for more info).
FP is not checked anymore.
v2 (Brian Paul):
* MESA_DEBUG accepts a comma-separated list of parameters.
* Clarify how MESA_DEBUG behaves with mesa debug and release builds.
* Updated wording.

Tried to answer all the comments from previous review on the
documentation itself.
Initially I had the following paragraph as an extra explanation:
"MESA_DEBUG=1 on release builds is equivalent to the default behaviour
of debug builds. MESA_DEBUG=silent on debug builds is equivalent to
the default behaviour of release builds."
But I think that is not needed, as should be understood from the
documentation.
