The bounding box calculation of text elements uses the terms "glyph
cell" and "full glyph cell". I assume textPath and tspan also uses
them.

Can you add clear definitions for "glyph cell" and "full glyph cell"
to the spec? Thay haven’t been defined anywhere and there has been
some confusion what they mean [1][2].

Thanks,
Kari
