Comment(by hamish):

 I notice in wxpython/core/render.py sets GRASS_COMPRESSION=0, but that
 doesn't exist, GRASS_PNG_COMPRESSION does. Having that mis-set probably
 doesn't help rendering speed & cpu load any.

 broken since forever; fixed in all branches.


 wrt the tempfiles mentioned in comment:10, I wonder if we can at least
 mitigate the left-over-file problem (#560) by putting them in the GISRC
 tempdir with something like:

 {{{
 tempfile.mkstemp(suffix = '.ppm',
    prefix = os.path.basename(os.path.dirname(os.getenv('GISRC'))) + os.sep
 + 'tmp_')
 }}}


 (? is the GISRC enviro var reset in core/render.py there for the GCP tool,
 or..?)
