A little more glyph tweaking.
Screen label icons have their own size.  Active vector object now using the correct subdivision algorithm.  Fixed a min/max height return problem in the maply view controller.  Turned visible range banding back on.  Tweaked the glyph display just a little bit more.  Everything seems to be lined up right.  Fixed a bug in the screen space calculations for quad paging when dealing with extreme view matrices.  Fixed a problem in the chunk layer with non-square textures.
