[Mesa-dev] [PATCH] i965: Delete "fast color clear unsupported" performance warning.

[Kenneth Graunke]

Applications frequently clear to colors other than 0.0 or 1.0, which
prevents us from doing fast color clears.  In that case, we issue this
performance warning on basically every glClear call, resulting in so
much spam that it's nearly impossible to see any other messages.

Plus, I don't think it's useful.  We aren't suggesting a better way to
do what the application developers want---we're just telling them it
would be faster to do something they don't want.

Driver developers have no control over the clear color, so this message
is totally useless to them.
