Well, my 8 core/16 thread machine is pretty fast as-is, but...

My 40-mesh blur example, at 800X600 and no AA (and no 'vignetting' or
'distortion'), took a total of 2min 15sec (!)-- of which about 16 sec was the
parse time. Pretty amazing. (I did turn off the radiosity that was in one of the
meshcam includes though.) I guess most of the parse time is spent constructing
the single mesh; it's done in SDL in 'meshcam_macros.inc', not internally. By
saving the mesh on the first go-round, subsequent renders will be even faster--
which makes it easier to experiment with the motion-blur, since the mesh itself
doesn't change.
