Fix WB font-based piece rendering on variant switch

The piece bitmaps were only created from the font characters when the
number of ranks or files changed, because it was done in
InitDrawingSizes(). This caused missing pieces when changing to a
variant on the same board that used other pieces. Now InitDrawingSizes()
is called for any variant switch.
