Basically the code will extrude the different paths (sorted by colour) from inkscape and linear extrude on the openscad.
*Lines will linearly extruded and the thickness should be adjustable,
*Different heights for different coloured lines,
*Filled polygons will be extruded as whole (not just the lines)
*A different filled colour will be removed from the extruded main part (difference)
These are the main bullet points, I have a similar extension but lacking the remove the difference option.
