Reviewed by Antonio Gomes.

After the last calling sites of blitContents() have
been removed or reworked, the actual method itself
can now retire. All blits now go through
blitVisibleContents(). The knowledge that we always
blit the full visible surface can facilitate further
optimizations; we will get to that in time.
