Bugfix inverted whitspace:
In the print substring function white spaces are bypassed by just increasing the drawing position without really putting a pixel on the screen. As results white space were not draw as yellow boxes resulting in a bad inverted string visualization. => Changed implementation to not bypass inverted white spaces.
