Subject: st/dri: add drisw image extension
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bbdeddd5fd0b797e1e281f058338b3da4d98029d;p=mesa.git

st/dri: add drisw image extension

Since the revelant functions have been moved to dri_helpers,
drisw.c can make use of the extension. Note we have version 6
of the extension, since we want to support createImageFromTexture.
