Title: Re-saved PNG files that generated libpng warnings.

Some of the Qt GUI PNGs had invalid color profiles. This caused libpng
to emit warnings whenever they were opened (by any code using highgui
with Qt enabled). I fixed this by opening and re-saving them using
python's PIL.

One of the logos also generated a libpng interlacing warning which was
fixed the same way.
