From 8ef6ff17653e54c8b799bc89350e8d3342849d13 Mon Sep 17 00:00:00 2001

Subject: This may cut down a little on unnecessary strings / mallocs:

* Only create the self.[xywh] aliases and its variables if prefixedname has no
  periods in it, e.g. MusicText.x, but not MusicText.align.x

* Set the .r, .g and .b variables directly, rather than aliasing them through
  .x, .y and .w
