void printfGlyph

(

bmGlyph *

glyph

)

Two external functions:

void detectBitmapFont(ImBuf *ibuf) detects if an image buffer contains a bitmap font. It makes the specific bitmap data which is stored in the bitmap invisible to blender.

void matrixGlyph(ImBuf * ibuf, unsigned short unicode, *float x 7) returns all the information about the character (unicode) in the floats

Room for improvement: add kerning data in the bitmap all calculations in matrixGlyph() are static and could be done during initialization
