* @summary Verifies that the pixelization of simple primitives (drawLine,
* fillRect, drawRect, fill, draw) with the OGL pipeline enabled
* matches that produced by our software loops. (The primitives tested here
* are simple enough that the OGL results should match the software results
* exactly.) There is some overlap with PolyVertTest as we test both
* solid and XOR rendering here, but this testcase is a bit simpler and
* more appropriate for quick OGL testing. This test is also useful for
* comparing quality between our X11/GDI and software pipelines.
