LibGfx/Painter: Add draw_rect_with_thickness method

Browse source 
Previously there was no way to draw rectangles with any specific
thickness, like we can do with ellises, for instance. This method
is just a simple wrapper around `draw_line()` several times. At
least for now, we don't need to do anything sophisticated since
this will only be used by PixelPaint.`
