This patch churns a lot because it needs to change 4-wide filters into
single pixel filters, since each fragment may use a different filter.
The only case not entirely supported is the anisotropic filtering.
Not sure what we want to do there, since a full quad is required by
that filter.

A lot of code I just glossed over it, but seems to look ok other than
the (performance) implications this might have.
