25a7061652 * moved AGGTextRenderer alongside it's pal, Painter, it felt lonely,
removed font_support folder
* ServerApp can use ServerFont::StringWidth() directly again
* more ServerFont functions implemented via GlyphLayoutEngine and
  custom consumer
* extended GlyphCache data structure to hole the left/right insets
  of the glyph shape between its advance width, took it from the earlier
  ServerFont implementation, have not tested if that gives same result
  as R5
* TODO: implement GetGylphShapes via GlyphCache, although it might not
  look as clean as it does now

2222864eed * complete overhaul of the font/glyph caching
* the previous AGG implementation is superfluous
* the new implementation is based on that one, but in a way that allows
  read/write locking to the list of cache entries (fonts) as well as
  read/write locking to the cached glyphs per individual font cache entry
* new GlyphLayoutEngine.h, which is to be the central place for layouting
  glyphs along the baseline.
  It handles the locking for getting the font cache entries.
  It works by giving it a template class GlyphConsumer which does the
  actual work.
* changed AGGTextRenderer to use the new font cache
* changed ServerFont::StringWidth(), and the bounding box stuff to use it
* changed DrawingEngine, it doesn't need the global font lock anymore
* our BFont thought that GetBoundingBoxesAsGlyphs and GetBoundingBoxesAsString
  is the same, which of course it isn't, hence the two separate functions...
  AsGlyphs just gets the bounding box of each glyph in a string, not treating
  the string as an actual word
  AsString adds the offset of the glyph in the word to the bounding box
* changed ServerProtocol.h accordingly for the different bounding box meaning
