Initial attempt to Handle y offset of glyphs

(This is a work in progress, I've opened the PR for to get some feedback. The calculation I have - offset_y = glyph_info.geometry.y_offset / font_size / textbox.height does not seem to be accurate - since if the line height is large, the glyphs show up lower then they should.)

I assume that once we have a new version for pypdf, it will be 0.8.0

Thanks a lot!

The calculation I have - offset_y = glyph_info.geometry.y_offset / font_size / textbox.height does not seem to be accurate - since if the line height is large, the glyphs show up lower then they should.

That was glyph_info.geometry.y_offset / 1000 (1000 being a constant defined by Pango.)
