Add support for Latin-1, Cyrillic, and CJK characters inside \text{} (#508)

Browse Source 
Summary:
This diff provides support for Latin-1, Cyrillic, and CJK characters
inside \text{} groups.  For Latin-1 and Cyrillic characters we use
glyph metrics from a glyph from Basic Latin that has roughly the same
bounding box.  We use the metrics for a capital 'M' to approximate the
full-width CJK characters.  Half-width characters are not supported yet.

Test Plan:
- make test
- make screenshots
