[Piglit] [PATCH 1/2] port ttexrect.cpp to piglit from glean

This ported test goes into tests/spec/arb_texture_rectangle. It
tests the ARB_texture_rectangle extension.
Create a 255x127 texture of varying colors and bind it as a
GL_ARB_texture_recangle target. Draw that rectangle to the window, and
check that the texture was drawn correctly. The common failure to be
caught with this test is not adjusting the non-normalized coordinates on
hardware that expects normalized coordinates.
