Is there a reason that we should not support all the formats that 
Graphics Magick does?  It seems like the best way to support all images 
would be to just let imread/imwrite try to read/write the image and if 
we get an error from Graphics Magick that the format is unsupported we 
pass that back to the user.  I don't see any reason to artificially 
limit ourselves to some arbitrary subset of image formats.

Have a good day,
