layer start needs a moveto(0,0)

[jnweiger]

It seems ruida driver assumes the laser head is always at position (0,0) when a new layer starts.
If the last coordinate of the first layer is not (0,0), and the first coordinate of the second layer is (0,0)
then the head does not moveto(0,0) -- instead it starts the second layer from the last point of the first layer.

Example file. Use green (mark) before red (cut):

This example does a false cut diagonally across the figure.

That is what it looks in VisiCut (all right):

That is what the bug looks like, cutting the green circle first, then the red rectangle:
