And for blitting, we don't do this at all, we draw textured quads -
the
texture is never modified after the initial upload normally. If you

to a texture, we use FBO.
Yes, I realised this after writing my post.
Really the only time this would be relevant is
al_lock_bitmap/al_unlock_bitmap - they could be optimized a bit.
(But in
general the question is, why would you use those in the first place?)
