[Piglit] [PATCH] arb_uniform_buffer_object/maxblocks: use larger window, set viewport

[Brian Paul]

Commit 42d2fdf changed the test to use the default window size.  But
even before that, the window was too small for common values of
GL_MAX_VERTEX/FRAGMENT/COMBINED_UNIFORM_BLOCKS so we skipped some
testing.

Now use a larger window and call glViewport() so that if we resize
the window we don't blow up.

Finally, print a warning if the window is too small in the future.
