Hi John,

	I guess gnome-love gnome org is more appropriate for this kind of
thing.

	Do you mean anti-aliasing ? if so - the canvas has a mode which you can
turn on to do that (one of the initial shady design decisions).

	Mostly this is a terrible idea; IMHO it's a feature that it's hard to
do.

	So what color do you want to set it to ? what if the theme uses that
color for the background ? will a different coloured menu give the user
the heebie jeebies - given that no other app does this sort of evilness
;-)

	Cast GTK_BIN(menu_item)->child to a GTK_LABEL and poke at that.

	Then simply ensure that your canvas requests a really small size; like
2x2 - and you can fiddle with it on 'size_allocate'. It's a bad idea to
allocate less than the request I'm sure.
