Subject: meta: Move bind_fbo_image() code back to meta.c, to reuse it elsewhere.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cd808ac848227b850a80c1adbb43ce57ca7d673a;p=mesa.git

meta: Move bind_fbo_image() code back to meta.c, to reuse it elsewhere.

I need to do the same code again for CopyTexSubImage().

v2: Drop incorrect, not-terribly-useful comment (review by Ken)
