This tool is able to convert an X11 PCF font to Serenity's font format. These pcf files are a fairly common bitmap font format, and with this we are easily able to use many of them.

Could also turn this into a parser in LibGfx, not sure what makes more sense. |

Should we we validate property types?

Should we check that min < max?

Does this happen? Should we error out instead?

Can this be larger than u16? The mapping only has 16bit values for min and max afaict.
