Changed widget API to be more compatible with the standard Tcl API.
The following operations invoked via "<widget> cmd <op>", where
<op> is:

  plgcmap0 plgcmap1 plscmap0 plscmap1 plscol0 plscol1

have been replaced to calls to their Tcl API variants.  The syntax is changed
(instead of Tcl lists's, Tcl Matrix's are used) so this is a potential
incompatibility with old codes.  On the other hand, codes that employ the
standard Tcl API will now work correctly.

The old operations are now available by the following widget commands,
i.e. "<widget> <op>" (note no more "cmd"), where <op> is:

  gcmap0 gcmap1 scmap0 scmap1 scol0 scol1

for codes that want to use the previous syntax (e.g. palette tools).
