[Gnash-dev] OpenGL Video Scaling

[Quinn Storm]

It turns out the reason OpenGL videos aren't being scaled properly is the 
current OpenGL code doesn't take into account the implicit scale caused by 
the viewport not matching the movie coordinates, which is fine everywhere 
except in video drawing b/c video drawing doesn't take into account the 
projection matrix(I think) since it just uses glDrawPixels.  I've provided a 
patch which properly calculates the values to pass to glPixelZoom, but I am 
running into an obnoxious bug in my OpenGL implementation here (i915/945GM) 
where the leftmost few columns have a transparent line through them at the 
top of each source pixel.
