- There is a bug here. I verified the failure on my Elan and hopefully
- it will be fixed in the "next release." 4 bit images are supported
- thru software un-packing, but 1 bit images should work using hardware
- unpacking.

- They should work, when the man page is referring to Indigo, it means
- the Indigo Starter graphics. XS/XS24/Elan should support almost
- all pixmodes either in hardware or software emulation. The man
- page notes that PM_OFFSET != 0 is not supported.
