gtk:window-set-geometry-hints (window geometry mask)

window -- a gtk:window widget
geometry -- a gdk:geometry instance containing geometry information
mask -- a gdk:window-hints mask indicating which geometry structure fields should be paid attention to

This function sets up hints about how a window can be resized by the user. You can set a minimum and maximum size. Allowed resize increments, e.g. for xterm, you can only resize by the size of a character, aspect ratios, and more. See the gdk:geometry structure. In the Lisp implementation an unused widget argument is omitted.
