It is not possible to invert a single pixel with u8glib. However it would be 
possible to create a picture like in your image: Write the bitmap not inverted 
and complete first. Then draw the progress bar,then draw the bitmap again, but 
with inverted pixel and only that part of the image which overlaps with the 
progress bar.
