Carnë,

According to the Matlab documentation, input images for rgb2gray and
rgb2hsv can only be of type double, single, uint8, uint16.  However, the
input validation is also accepting int8 and int16:

    if (! any (strcmp (cls, {"uint8", "int8", "int16", "uint16", ...
                             "single", "double"})))
      error ("%s: %s of invalid data type '%s'", func, arg_name, cls);

Should we remove support for int8 and int16, or is there undocumented
Matlab voodoo and images of those types are accepted?

I've finished up with rgb2gray, except for this issue.
