I would like to create a convertor from gl values to pixel values
For example, in gl world, the position should be in -1 1 format.
I would like to convert it in pixel, so the center of picture would be 512- 384 for a 1024*768 screen.
And I want to know it for every point (Keystone (ABCD), center,…
To complicate a litle bit, i would like to do this dynamicaly, whatever is the screen size (with jit.displays)
