+ *
+ *  Test basic GL rendering paths.
+ *
+ *
+ *     Based on the original Glean tpaths.cpp test, this test verifies
+ *     that basic, trival OpenGL paths work as expected. For example,
+ *     glAlphaFunc(GL_GEQUAL, 0.0) should always pass and
+ *     glAlphaFunc(GL_LESS, 0.0) should always fail.  We setup trivial
+ *     pass and fail conditions for each of alpha test, blending, color mask,
+ *     depth test, logic ops, scissor, stencil, stipple, and texture and
+ *     make sure they work as expected.  We also setup trival-pass for all
+ *     these paths simultaneously and test that as well.
+ *
+ *     To test for pass/fail we examine the color buffer for white or black,
+ *     respectively.
+ *
