Subject: Changed Font code to use glyph.offset, instead of Rect() for variable width fonts...

Changed Font code to use glyph.offset, instead of Rect() for variable width fonts, as using Rect leads to shadows being cut off

 * add a (border #t) flag to fonts, that allows to use fonts which have
   a 1px transparent border around glyphs, which is needed to get rid
