If you are creating temporary images which will be read by another
program then deleted, there's no point wasting CPU cycles on
compression.

Having said that, I would guess that the XWD option corresponds to
using xwd to grab the contents of an XDRIVER window. Similarly, I
would guess that the TIFF option corresponds to using the CELL driver
plus r.out.tiff.
