Regression with font rendering in 1.11.

With the new 1.11 firmware texts are now hard to read. The rendering somehow seems off.

There are some characters that especially hard to read:

• "a" sometimes looks like "o"
• "l" and "i" are hard to tell apart.

Also the font sizes seem to have changed somewhat, which leads to unexpected line breaks in different apps, e.g.:

• battery_info: Units are now sometimes rendered in a new line, which renders values unreadable.
• Sleeptracker: The lines "touch" each other vertically and the timer in the bottom left is unreadable.

Also it looks a little bit as if a font with proportional letter widths is used as a monotype font.
