[PD] making gem units be pixels

[Thomas Grill]

Hi,
for that i normally use abstractions that do the coordinate  
transformation after the gemhead without changing the camera (see  
attachment: vis-test uses the other files).
But, since for a project i'm working on a more general solution for  
simple UI widgets in gem including mouse and keyboard interaction,  
that brings me to the question if anyone has already done something  
like that. One would assume yes....
gr~~~
