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. To all.tests, add new texrect_simple_arb_texrect v2: add PIGLIT_GL_VISUAL_DOUBLE to the window_visual, move various setup bits to piglit_init and add forgotten all.tests change.
