+Depth, Stencil, & Alpha
+=======================
+
+These three states control the depth, stencil, and alpha tests, used to
+discard fragments that have passed through the fragment shader.
+
+Traditionally, these three tests have been clumped together in hardware, so
+they are all stored in one structure.
