Question about rotary toolpath display.

master branch:

> 9. Rotations are by default applied with respect to the machine
> origin. Example: GEOMETRY=CXYZ first translates the control
> point to X,Y,Z and then performs a C rotation about the Z
> axis centered at the machine origin.
>
> 10. Rotations applied after translations may use the "!"
> provision to to act with respect to the current machine
> offset. Example: GEOMETRY=!CXYZ translates the control point
> to the X,Y,Z position and then performs a C rotation about
> the machine origin displaced by the current G5x,G92 X,Y,Z
offsets. (Changing offsets may require a program reload).
