gfx: Fix line drawing + symmetry tests
The Bresenham's line does not draw symetric line by default, if you want
line that is symmetrical when mirrored horizontally or vertically or
when rotated by multiples of 90 degrees you have to draw only half of
the line and draw second half symetrically to the line center.
