+/* KW: Added lots of surface formats to support vertex element layout
+ * definitions, and eventually render-to-vertex-buffer.  Could
+ * consider making float/int/uint/scaled/normalized a separate
+ * parameter, but on the other hand there are special cases like
+ * z24s8, compressed textures, ycbcr, etc that won't fit that model.
