Subject: glsl: move xfb BufferStride into gl_transform_feedback_info
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f5a6aab4031bc4754756c1773411728ad9a73381;p=mesa.git

glsl: move xfb BufferStride into gl_transform_feedback_info

It makes more sense to have this here where we store the other values
from xfb qualifiers. The struct it was previously part of is now only
used to store values that come from the api.
