Adafruit GFX Pixel font customiser

This is a handy utility that goes well with the original fontconvert tool provided by Adafruit for converting TTF fonts to Adafruit_GFX .h format.

Just paste the content of a .h font file, extract the glyphs, and you can edit them one by one by flipping the individual pixels for each glyphs, changing the advance, offset, or modifying the baseline.

You can then process our changes and create the improved file.

This is useful since the fontconvert utility does not always create all the characters correctly (a missing pixel here and there). It works best for small size fonts (< 12pt).
