- block of memory that contains 1024 32-bit values that can be set

- following actions for each glyph:
-
- - render the glyph
- - store the address of the glyph bitmap in user_info[5]
- - store the width of the glyph bitmap in user_info[6]
- - store the height of the glyph bitmap in user_info[7]
- - store the font's ascender into user_info[8]
- - store the font's height into user_info[9]
- - store the glyph's ascender into user_info[10]
- - store the glyph's advance into user_info[11]
-
- The VM will then pause after each glyph. The VM should not be
- unpaused after the last glyph until the next glyph set has been
- configured in user_info (ie it does not pause twice).
