The texturing code does use bilinear interpolation. For larger scale
factors, we could even generate mipmaps and use the rest of the 3D
engine.

Of course, the overlay does a lot more sophisticated filtering than
that; it has a multi-tap FIR for scaling the video (not sure how many it
uses, but iirc, it's like 5 or 7)
