Display Buffer

file
robolib/display_buffer.h

description
The display buffer modul contains functions for printing data to a display. In contrast to the display modul the data is first saved in a virtual display (buffer). When updating the whole display is synchonized with virtual display. But only changed characters are printed.

The virtual display can be smaller, but should not be larger than the display in use.

There will be no automatic linebreak at the end of a virtual display line.
