-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.
