+ * @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.
