coordinate, only noticable in Panel versions of picker
- the fix to give Transform properties new name "Paint" can't
work with this code... this due to fact that panel positions are saved
in files or looked up on re-open based on their names. Giving the Panel
a new new name then causes it jump to another position, and back on end
of painting.
Needs to be solved in another way. Not feasible for 2.34...
