Work in progress... improvements on font stuff, reverted to using Painter to get the string width. Since it actually uses glyph caching, it is about 20 times faster than the implementation in ServerFont (and a about twice the time as R5). I added a StringWidth method to Painter and AGGTextRenderer which works as correct as ServerFont::StringWidth, which btw was broken, because I mixed up glyph count and byte count...
