utility APIs designed to expose the features of 3D graphics hardware using

a direct state access API design, as opposed to the state-machine style

of OpenGL.

All of the tests except for the ES2 and ES2-NPT tests are broken due to
|
|
slight behavior changes in Mesa. To test the results anyway, issue:
|
|
<command>make check</command>. The tests should be run from an X terminal
|
|
on a hardware accelerated Xorg Server. A few tests will use all CPUs in
|
|
parallel, regardless of parallellism settings.
