    I have added some isOnScreen logic to
    fl_BlockLayout::redrawUpdate() and fp_Line::redrawUpdate(), the
    latter now returns true if the line is on screen and false if not and
    redraw is only done in the former case.

    I would like to do something similar to the format mechanism, but my
    early effors seem to indicate that it will not be that straight forward.

    files: fl_BlockLayout.cpp, fp_Line.h/cpp
