Problem
A character (like U+2588 FULL BLOCK █) that uses the full glyph height will overflow the actual in-game character grid. For existing glyphs, this is not a bug.
However, when adding new glyphs, it is useful to understand the "real" bounding box that you're working with, so you can size and position the glyph accordingly.
Context
One way to solve this could be adding a "reference bbox" glyph somewhere. Alternatively the bbox (in font units) could just be written down somewhere.
I would like to compute bbox as accurately as possible (in font units) but I am not sure how to do this yet. It should be fairly easy to give a rough (but useful enough) approximation, though.
