Routine Description:
  Translates a Unicode character into the corresponding font glyph.
  If the Source was pointing to a non-spacing character, the next Source[*Index]
  character will be parsed and OR'd to the GlyphBuffer until a spacing character
  is found in the Source.  Since non-spacing characters are considered to be the
  same pixel width as a regular character their BitWidth will be reflected correctly
  however due to their special attribute, they are considered to be zero advancing width.
  This basically means that the cursor would not advance, thus the character that follows
  it would overlay the non-spacing character.  The Index is modified to reflect both the
  incoming array entry into the Source string but also the outgoing array entry after having
  parsed the equivalent of a single Glyph's worth of data.
