+/** @file paths.c
+ *
+ * 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.
