commit 2752018e27420947a034d50f1ce165bbb76ae1a8
parent 0d88f1ef75c2fe9403a72c80d6fa8ed199ec474f

This adds the fontcache dependency to try something out. Additionally the

invert mode now works as expected. In the config.def.h autohint is set to
false, so the fonts are drawn correctly, without any overlapping.
