[PD] [pix_crop] for texture from [gemframebuffer]

Iohannes is right.
The example i pointed out consumes quite some cpu-power.
but: in the help-browser you´ll find another example, that takes the 
texture id of a framebuffer and allows to "crop" the texture. in this 
example, the work is done by the gpu with the help of glsl-shaders.


regards peter
