 - trying to optimize the resulting geometry in DXF import (and in SVG import) by merging contiguous lines; reduced the lines to about one third of the original
 - fixed importing DXF file as Gerber method such that now the resulting Gerber object is correctly created having the geometry attributes like self.apertures and self.follow_geometry
