The original results were with olvwm (Open Look), and I tried with icewm
with the same results. I attempted to tile the windows, but when they
first appear they are overlapping, and after that the main raster display
is immovable. It takes about 10 seconds for the windows to flash and the
screenshot to save, so I'm able to get one screenshot every 10 seconds or
so. I'm also getting the error message:

*** event raised for warning: WarningMessage
*** function: tkobjc_pixmap_create_from_widget(), file: internal.m,
line: 1291
Window manager won't allow map

Is there a way to dump the raster directly rather than go through a window
manager? (If not I have some old code that outputs gifs that could be used
for this purpose).
