[Mesa-dev] [PATCH 2/8] i965: Stop worrying about alignment of vertex data.

[Eric Anholt]

For our current types, the required alignment is actually just 1 byte.
When we get doubles, we have to worry (those have to be aligned to the
natural size), but we don't have doubles yet and they'll just be a
special case.
