compute_point

Description:

public bool compute_point (Widget target, Point point, out Point out_point)

Translates the given point in this's coordinates to coordinates relative to target’s coordinate system.

In order to perform this operation, both widgets must share a common ancestor.

this	the `GtkWidget` to query
target	the `GtkWidget` to transform into
point	a point in this's coordinate system
out_point	Set to the corresponding coordinates in `target`'s coordinate system

true if the point could be determined, false on failure. In this case, 0 is stored in out_point.
