Technically: yes.
But from a users POV the bilinear texture filter never said "(slower)" (tho=
ugh the css nvidia driver is pretty fast on bilinear xrender scaling - no i=
dea about other HW, though...)

In general i'd perhaps avoid filter terms at all and use sth. like "Crisp",=
 "Smooth", "Accurate", "Extra accurate" ... or so (though this would force =
TriLF to get the lanczos filter)

Reason:
We cannot pre-catch every required gpu/driver in the blacklists and since blacklists \
are vendor utils, users cannot be expected to fetch the proper driver string and \
extend the list by themself in case they encounter a problem.

Behaviour:
There&#39;s a new &quot;smooth scaling&quot; tristate checkbox, replacing the XRender \
