AFAICT, VR is measured in angles. It does not matter if you move one pixel 
within the window resolution, or one sample within the video resolution. And 
if the video is upside down, then going up in the window coordinates should go 
down in the video coordinates and viewpoint angle.

At the input & itnterface levels, the window resolution is meaningless. In 
fact, it's neither known nor fixed.


Certain things are broken. Most likely gestures for one. But adding events for 
cursor position in window coordinates fixes nothing.
