-- specified by group rather than as a specific item. A single-item group
-- is represented by that item, with the single-item status signalled
-- so that stack_image_button() can treat it as just the item. If the
-- group contains no items at all, it will be treated as containing a
-- single unknown item.
--
-- Within a multiple-item group, we prefer to use an item that has the
-- same specific name as the group, and if there are more than one of
-- those items we prefer the one specified by the default mod if there
-- is one. If this produces a bad result, the mod defining a group can
-- register its preference for which item should represent the group,
-- and we'll use that instead if possible. Also, for a handful of groups
-- (predating this registration system) we have built-in preferences
-- that are used like registered preferences. Among equally-preferred
-- items, we just pick the one with the lexicographically earliest name,
-- for determinism.

-- 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, the group will be
-- represented by some item in the group, along with a flag indicating
-- that it's a group. If the group contains only one item, it will be
-- treated as if that item had been specified directly.
