* 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
