Sorry, I was wrong. The readout can be changed for both X and Y, so a flip
is possible without changing the rest of the code. (Actually, the display is
normally operating upside down the way we program it). I just tried, it works.
The only additional change it that I have to add 20 pixels for the X
addressing, since the internal framebuffer is 132 pixels wide, versus we have onle
112. I we want the display at the same "edge" as befor, we have to add 20.
I will commit this change soon, I'm working on the LCD module anyway.
The question now is, where to put that config option, and do we want it as a
persistent setting? Also I found that the buttons should be remapped, too,
else it's _very_ irritating.
