+ * 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.
+ *
+ * As of Ivybridge, the columns are no longer in that table and the
+ * information can be found spread across:
+ *
+ * - VOL2_Part1 section 2.5.11 Format Conversion (vertex fetch).
+ * - VOL4_Part1 section 2.12.2.1.2 Sampler Output Channel Mapping.
+ * - VOL4_Part1 section 3.9.11 Render Target Write.

- * it in our table, here's the mapping:
- *
- * Y*: 45

- * 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.
- *
- * As of Ivybridge, the columns are no longer in that table and the

- *
- * - VOL2_Part1 section 2.5.11 Format Conversion (vertex fetch).
- * - VOL4_Part1 section 2.12.2.1.2 Sampler Output Channel Mapping.
