PI40 documentation

It would be nice to have documentation for the PCB connections of the IP40 screen (GPIO port, switch, PWM, and ON/OFF pads). I'm especially interested in using PWM to dim the backlight.

I also noticed that the driver provides wrong values for the physical dimensions of the display. It uses 74 x 49 mm while measuring the display gives 83 x 56 mm. As a result Qt applications using the frame buffer driver will show text using pt sizing too large.

Thank you in advance
