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