Inventory scrolls when dragging items over inventory arrows (to make it possible to use items on items that aren't on the same "page"). This works a bit iffy. For example, trying to drag past the leftmost item on top of the left arrow, seems to leave the leftmost item glow on.
Some ideas:
Glow on inventory arrows
Don't glow on the item next to arrow (obviously)
Objects in rooms have .cache() and .drawHitFromCache(); not honestly sure what that does, but maybe it might help?
