On Windows XP, with font backend enabled, Emacs costs 100M or more
memory


It's "only" 87MB for me, but that is also way too much.
The bug should be fixed now, the minimum width and height of characters was being initialised to 1 (pixel), and not updated to the real value by the new font code, so redisplay was allocating far more memory than it needed to keep track of the displayed characters.
