Detailed Description

Exports the frame buffer to a PNM file.

The frame buffer size needs to be mannualy set. Beware of screen resizes. Please fix this by creating a resize handler for viewers.

PNMs are as bad as BMPs. Saving several frames will eat all your HD space. Please fix this by creating a PNG exporter :-).

A PNMExporter is a ViewerGlutOGL::DrawHandler that reads the frame buffer and writes it to a file. Created to make videos from V-ART display.
