Yes. Excellent points. This type of wrapper has uses best suited to
quality mavens with a lot of extra hardware or ultra-limited hardware
(without gl support). Usually I trust a slow resource-intensive
software scale over a hardware scale when it comes to raw quality
(maybe this is my ffdshow / zoomplayer roots showing) though I'm
welcome to entertaining thoughts to the contrary. Bicubic spline is a
/slow/ scaler but the results are very pretty as are those of lanczos.

If I find time this weekend I'll load up a low res video (probably one
of the 'bonus disc' original star wars theatrical releases --
widescreen inside a 4:3 letterbox rips to an image about 300 pixels
high) and grab some screenshots of the sws and the gl.
