*
* Use this widget instead of #GtkPixmap if you don't want to worry
* about the parent container's "realized" state.
*
* Note that the drawback of the easy interface is that the actual
* #GdkPixmap and it's mask have to be constructed every time you call
* gimp_pixmap_new() and cannot be cached in memory without doing bad
