[Octave-bug-tracker] [bug #41851] ind2rgb values outside range of colour map

[Carnë Draug]

Follow-up Comment #11, bug #41851 (project octave):

Rik, as an alternative, please take a look at the attached patch. It is an
amend of yours.

It makes note of this bug number in the comments, prints a warning for the
opposite case (colours above the cmap limit), and tests that warnings are
issued for 0, off by one errors for integers and floats.

Also, it performs just a tiny little better (since we don't need isindex to
check if all values are integers again) and avoids "x(x < 1) = 1" unless
absolutely required which always creates a copy of the image.
