To make sure we're on the same page, I made an error in using the term
clear address, because the code only checks part of it (the bo)?
What do you think of this new commit message?
i965/wm_surface_state: Use the clear address if clear_bo is non-NULL
We want to add and use a getter that turns off the indirect path by
returning zero for the clear color bo and offset.
v2: Fix usage of "clear address" in commit message (Jason).
