+ block of memory that contains 1024 32-bit values that can be set
+ with the setUserInfo() method of MIPSEmu.
+
+ The VM will pause after initialization. When unpaused, it expects
+ that:
+
+ user_info[0] = ptr to font byte stream in memory
+ user_info[1] = length of font stream
+ user_info[2] = unicode index of first glyph to render
+ user_info[3] = unicode index of last glyph to render
+ user_info[4] = point size to render in
+
+ The VM will then iterate over the requested glyphs, performing the
+ 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).
