This renders all the slices across the window, and all 4 tests
down the window, it also doesn't bail on failure quite so early
so you can use it to debug all stages at once.

glGenerateMipmap doesn't make sense with integer textures. It all fails
with fglrx. Unfortunately, the specification is silence on this.

Feel free to let me know if you think otherwise.

accidentally broken when fixing GL_DEPTH32F_STENCIL8

Multi-pass algorithms that compare fragment Z to a depth texture sample
can exercise this sort of thing.

Replaced poolName in the Test constructor with runConcurrent
boolean option.  runConcurrent defaults to False.  When True, the
Test pushes its doRunWork to the ConcurrentTestPool to be executed
in another thread.  When False, doRunWork is executed immediately
on the calling thread (main thread).

Remove ThreadPools from threads module since it is no longer
needed/used.  ConcurrentTestPool is now the only threadpool needed
to manage cpu-only tests.

This is an intermediate change that moves the "base" (or gpu)
tests to the main thread and the other (cpu-only) tests to the
ConcurrentTestPool threads.  This restores ctrl-c behavior for
gpu tests.

The ConcurrentTestPool singleton will simplify the threading model
and remove the need to manage multiple ThreadPools.  Only one
threadpool is currently needed at this time and is meant to execute
cpu-only tests in separate threads.

This is unimplemented in Mesa, unfortunately.
Passes with fglrx.

This should hopefully fix linking failures.

Discussed on IRC.

Finally we have headers for OpenGL 4.1 and all the extensions released
to this day.

I've only tested ARB_texture_float, but the others should work too.

There is also a similar test arb_color_buffer_float-clear,
which is more thorough.

I've had this patch on my hdd for long time...

Reproduces Mesa bugzilla #34198.
