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