Add new function isgraphics() for Matlab compatibility.
Change over existing instances of ishandle to ishghandle.
* NEWS: Announce changes.
* scripts/plot/util/isgraphics.m: New function.
* scripts/plot/util/ishandle.m: New function.
* scripts/plot/util/module.mk: Add isgraphics.m and ishandle.m to build system.
* plot.txi: Change documentation around ishandle. Add isgraphics DOCSTRING to
manual.
* graphics.cc (Fishghandle): Rename function from ishandle to ishghandle. Add
seealso links in docstring.
* graphics.cc: Rename all instances of is_handle to is_hghandle.
