Negative values (which Coverity didn't complain about) could also
cause problems.
+ - the Imager::Color set_internal() interal method no longer
+ calls the over-complicated ICL_set_internal() (which is retained
+ only for the old API.) Coverity complained that this leaked, but
+ this could only occur with an invalid (NULL pointer) color object.
+
+ - the underlying implementation of the map() method could read before
+ the beginning on an allocated array if supplied with inconsistent
+ parameters, which Coverity complained about. No Imager code calls
+ that function with inconsistent parameters, but a
+ belt-and-suspenders check was added.
+
+ - Coverity complained a call to i_getcolors(), used by the
+ implementation of the is_bilevel() method could leave the fetched
+ colors uninitialized. Added a return value check.
