Draw grid
That makes glyphs easier to read.
Move the glyph info's grid function in the glyph drawing class and allow to put them on each glyph.
Possibility to define via css:
- display the grid or not
- grid mode: points, lines
- line(s) to draw or not: upper, middle, bottom
- half-shifting to pass through the pixels or between them
