Comment:

 (In [8736]) Fixes #1079, and speeds up scaling.

 This grabs the preview from within the output loop, so that it is
 impossible for a slow scaler/yuv2rgb converter to get parts of two frames.
 This also speeds up the process 4 to 5 fold by scaling the frame before
 converting it to RGB, instead of the other way around. This is on my
 machine with MMX, I wrote the fix with the RGB conversion before the YUV
 scaling as well for timing purposes and that version is attached to the
 ticket, so anyone without MMX can test both approaches.
