56  * a pixbuf has been drawn to - this function returns this information in a
57  * BangPositon. This will allow an aggressive caller to bang the GdkDrawable
58  * directly instead of using conventional methods of setting the icon.
59  * Please understand: THE INFORMATION RETURNED CAN BE WRONG AND/OR OUTDATED!

61  * easily exist.
