Redo bold

[datMaffin]

• make it more bold (currently it is at 20. Try 30 - 40.)
• make sure the following glyphs look good:
  • regular: a, e, g
  • italic: e
  • Chalkboard bold letters (and other math symbols)
• Check how different fonts have implemented their bold
  • Source Code Pro (mentions that it took a bunch of time)
  • Ubuntu Mono (just like the font)
  • Julia Mono
• Check what to do with Box-Drawing (probably make sure that they are not embolden) and other special characters

Julia Mono research (uses a 2048 grid => double the grid size of mine)

• Latin alphabet: width and height increased by 50%
• Math symbols: width and height increased by ~10% to 30%
  • about 20pt
  • Some math glyphs were not embolden at all! (mostly pretty complicated glyphs)
• Braces: width increased by ~20 to 25%
• Math letters U+1D400 - ... do not change their shape
• Symbols did not change their shape

Source Code Pro research (uses a 1000 grid)

• really fat
• Latin alphabet: width and height increased by ~60pt
• Symbols that were thinner: width and height increased by ~40pt
• Box drawing characters are embolden

Ubuntu Mono research (uses a 1000 grid)

• Latin alphabet + Ascii Math: width and height increased by 50%
• Box-Drawing unchanged
• Math-letters unchanged
• Math operations: mostly same as latin alphabet; smaller details in the operations are not embolded as much

How to embolden (ideas):

• In general: 35
• Symbols, like mathematical symbols: 25
• Smaller details within other letters (like strike through): 25
• Detailed glyphs: 25. Check if mixing 25 and 35 looks good.
• Chalkboard Bold: 20
• Check that whole categories of glyphs are embolded the same
  • Currency symbols

Fine Glyphs (with ~77 width, 60 height) embolden only 20.

This is still on a pretty low priority...

I was thinking, however, that it would make sense to instead of replacing the current bold to add an additional darker style.
Rename the styles accordingly.

Alternative idea: make the regular style thinner. The regular style of other fonts (like source code pro) are also comparatively thinner.
