[Mesa-dev] [PATCH 10/10] mesa: Remove unneeded bitfield widths from the VAO.

[Mathias.Froehlich at gmx.net]

From: Mathias Fröhlich <mathias.froehlich at web.de>

With the current VAO layout we do not need to make these
fields a bitfield. We get a tight struct layout with this change
for VAO attributes.

v2: Change unsigned char -> GLubyte.
