+ * This is the table of support for surface (texture, renderbuffer, and vertex
+ * buffer, but not depthbuffer) formats across the various hardware generations.
+ *
+ * The table is formatted to match the documentation, except that the docs have
+ * this ridiculous mapping of Y[*+~^#&] for "supported on DevWhatever".  To put
+ * it in our table, here's the mapping:
+ *
+ * Y*: 45
+ * Y+: 45 (g45/gm45)
+ * Y~: 50 (gen5)
+ * Y^: 60 (gen6)
+ * Y#: 70 (gen7)
+ *
+ * The abbreviations in the header below are:
+ * smpl  - Sampling Engine
+ * filt  - Sampling Engine Filtering
+ * shad  - Sampling Engine Shadow Map
+ * CK    - Sampling Engine Chroma Key
+ * RT    - Render Target
+ * AB    - Alpha Blend Render Target
+ * VB    - Input Vertex Buffer
+ * SO    - Steamed Output Vertex Buffers (transform feedback)
+ * color - Color Processing
+ *
+ * See page 88 of the Sandybridge PRM VOL4_Part1 PDF.
