assigning a bit depth other than 8, 16, or 32

I'm not sure whether this qualifies as a bug, or maybe a request for a 
feature.

I am trying to write a dpx file using  GraphicsMagick, and I can't 
because I can't set the bit depth to 10 by calling myimg.depth(10) (it 
rounds it up to 16). This behaves exactly as documented, but it prevents 
my image from being written properly to dpx.
I tried commenting out the part of the code that rounds 10 up to 16, and 
it wrote my image correctly. It would be nice if the depth method had an 
optional flag called round (or something similar). If round is true 
(which would be the default behaviour) it will behave as it currently 
does, if round is set to false, then you can set depth to any value that 
you want.

Thanks
