gtk_paint_foo - GdkWindow or GdkDrawable?

["muppet" <scott asofyet org>]

using custom GtkCellRenderers, and attempting to use a custom renderer in a
reorderable TreeView, i've discovered that when the row is being dragged, that
argument is a GdkDrawable (specifically, a GdkPixmap) rather than a GdkWindow.

the problem is that the gtk2-perl wrappers for the gtk_paint_foo() functions
attempt to verify that the 'window' arg is actually a GdkWindow, since that's
what the C call signature asks for.

however, from reading the source of gtk/gtkstyle.c, it appears that it's safe
to have the wrappers accept any GdkDrawable rather than specifically
GdkWindows.

is there any reason this is not true?

if not, should i log that as an API bug?
