Comment(by martinl):

 Replying to [comment:10 huhabla]:
 >  * The current wxGUI rendering approach using PPM and g.pnmcomp seems to
 be the most efficient considering the fact that the cairo driver is not
 yet available in the windows version of grass7. It seems to me that using
 PIL will not provide a large speedup benefit over g.pnmcmop especially for
 large images.

 small update: since r57542 GRASS 7 is built with cairo support also on
 Windows.
