[Tile-dev] Size grip widget added

[Joe E. <jen...@fl...>]

Now in CVS: a new 'ttk::sizegrip' widget, the gizmo
that sits in the lower right corner of a window
that users can drag around to resize the window.

Native appearance on Windows, Windows XP, and OSX.
(ttk::sizegrips are redundant on OSX, since Tk automagically
inserts one for you, but putting a ttk::sizegrip in can help
to keep other widgets lined up properly.)

No options or methods other than the standard ones;
all behaviour is implemented in the class bindings.

ttk::sizegrips can handle toplevels with gridded geometry,
but not those placed relative to the right or bottom
of the screen, i.e., if negative X or Y coordinates are
specified for [wm geometry].  

(Tk implements negative positions in a not-quite-ICCCM-compliant
way, which leads to bad interactions with some WMs when
resizing.  For the same reason, ttk::sizegrips only support
"southeast" resizing.)
