Subject: mesa: Replace use of _ReallyEnabled as a boolean with use of _Current.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ff9c3e8e5a22597c83505479e918981377f8fdf4;p=mesa.git

mesa: Replace use of _ReallyEnabled as a boolean with use of _Current.

I'm probably not the only person that has tried to kill _ReallyEnabled.
This does the mechanical part of the work, and cleans _ReallyEnabled from
i965.

I think that using _Current makes texture management clearer: You can't
have multiple targets in use in the same texture image unit at the same
time, because there's just that one pointer.
