Detailed Description

One glyph's record in a GFXfont: where its bitmap is, its size, and where it sits relative to the pen.

A glyph is drawn relative to the pen position (x, y), where y is the BASELINE, not the top:

• upper-left corner = (x + xOffset, y + yOffset) (yOffset is negative)
• next pen position = (x + xAdvance, y)
• next line = y + GFXfont::yAdvance
