Initial Comment:
This patch has previously lived as a comment to
cigaes's patch #670437, but I think it has now matured
to the point where it deserves a tracker item of its own.
The way I see it, the main advantage of this one over
the old one is that this can be combined with any
scaler, thus producing a smoother image.
The actual stretching algorithm is currently a stupid
"double every fifth line" kind of thing, but I imagine
it could be replaced with a bilinear filter or
something. I've added some comments about how I think
this can be done.
The patch only updates the normal SDL backend. Some
work may have to be done on the OpenGL backend as well.
