[FINAL] Fixing MOAIFreeTypeFont cut-off edges and adding glyph info to support finding the blank in Pounce

Isaac fixed some bugs with text getting cut off, and those are in here.  He also added a thing in renderTexture() and renderTextureSingleLine() that has it pass back glyph position information.  I'm using this in Pounce to figure out the X and Y coordinates of the blank on the rug.  :cat2:  I also added support for it to the latest version of Label.
