Add Short4 vertex attributes, and benchmark them as 4.12 colors
This is likely our best widely portable option for encoding wide gamut
colors that doesnt sacrifice too much performance. The benchmark uses
them as we're likely to do: 4.12 fixed point, in the destination color
space. We're using SINT vertex attributes for simplicity, so the encode
and decode are simple multiply/divide by 4096.
