gtk:cell-area-context-push-preferred-height (context minimum-height natural-height)

context -- a gtk:cell-area-context object
minimum-height -- an integer with the proposed new minimum height for context
natural-height -- an integer with the proposed new natural height for context

Causes the minimum and/or natural height to grow if the new proposed sizes exceed the current minimum and natural height.

This is used by gtk:cell-area-context implementations during the request process over a series of gtk:tree-model rows to progressively push the requested height over a series of the gtk:cell-area-preferred-height function requests.
