Subject: mesa: Remove unneeded bitfield widths from the VAO.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2d3c466add25e49692bd833742bf2a3aac0d3801;p=mesa.git

mesa: Remove unneeded bitfield widths from the VAO.

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.
