Error of 2D viewer when loading gcode files with G2/G3 arcs

Good catch. I had test this with 3D view as I had wrote a test macro for testing my firmware but never tried to test it in 2D view...

Guess I know where the problem is. This came with Python 10 introduced stricter type verification. We had a lot of troubles with this in the past (e.g. #1224). It seems to be one of the so fare not identified parts of the code in this module.

gviz.py, line 334+:

    def _arc_scaler(self, x):
        return (self.scale[0] * x[0],
                self.scale[1] * x[1],
                self.scale[0] * x[2],
                self.scale[1] * x[3],
                self.scale[0] * x[4],
                self.scale[1] * x[5],)

I will change this.

That was superfast! And yes, works perfectly.
