/**
 * 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.
