Generator does not ignore hidden layers

[pedjas]

While designing drawing for exporting to gcode, it is necessarz to save some objects within document but not to convert them to gcode.

Logical way is to put objects on layer and then hide layer. That is how it is done for printing.

Geocodetools does not follow this logic. It treats all paths in document regardless if they are visible or not. It should ignore paths that are not visible and not export them to gcode.
