Seems like a request for a change which is neither a bug or a feature.

There was a time when particular depths were required since some code 
would mis-behave.  Those times are long-gone in GM 1.2.  10 and 12 bit 
images have been in the test suite for several years.

I will simply remove the code which forces 8/16/32 and update the 
documentation to reflect the change.
