    app: in paint tools, fix cursor position in line mode when snapping to angle
    
    In GimpPaintTool, when not snapping brush outline to stroke, make
    sure to properly snap the cursor position to 15-degree angle
    multiples in line mode, not only when painting the line, but also
    during motion.
