Subject: Fixed Issue 326: TextRenderer corruption with certain text

Fixed four issues:
 - Regression in new segmenting and punting code causing
   ArrayIndexOutOfBoundsException due to not resetting the glyph
   uploader during punt.
 - Issue in same code where length and total advance were not being
   reset properly.
 - Incorrect handling in glyph-by-glyph rendering when backing store
   was using NPOT texture and GL_ARB_texture_rectangle.
 - Failure to punt when glyph code was out of bounds.

Checked in two regression tests for these issues.
