[PD] making gem units be pixels

after fuzzing around with 3d to pix conversions for the xth time, I 
thought it should also be possible to set the camera to a point that 
just allows to have all units in pixels with the 0/0 in the top left corner.
the only way to get this working was to set the camera to a negative z 
position and flip the upvector. the problem with that is, that all 
images will be vertically flipped, too.
so I wonder whether there could be a general gemwin switch to flip + and 
- on the y axis?
and again, it would be extremely cool to have a possibility to read out 
the curent size of the gemwin.
