-- stack_image_button(): generate a form button displaying a stack of items
--
-- Normally a simple item_image_button[] is used.  If the stack contains
-- more than one item, item_image_button[] doesn't have an option to
-- display an item count in the way that an inventory slot does, so
-- we have to fake it using the label facility.  This doesn't let us
-- specify that the count should appear at bottom right, so we use some
-- dodgy whitespace to shift it away from the centre of the button.
-- Unfortunately the correct amount of whitespace depends on display
-- resolution, so the results from this will be variable.  This should be
-- replaced as soon as the engine adds support for a proper item count,
-- or at least label placement control, on buttons.
--
-- The specified item may be a group.  In that case, an image_button[]
-- is used, displaying an image that just indicates grouping, with a
-- label giving the name of the specific group.  It very often happens
-- that the group name doesn't fit within the confines of the button and
-- gets cropped.  Group names are also not brilliantly readable against
-- the background of the group image.
