-------------------------------+--------------------------------------------
 If DWF file contains DOTS hatch pattern filled object, it will not render
 if AGG Renderer is used.

 Dots from DWF file are processed as lines with same  starting and ending
 coordinates(length is 0). Method _TransferPoints  from AGGRenderer class
 is not correctly handling lines that have length=0.

 Proposed patch works around this problem. If line length is 0 then line is
 rendered using value 2*LINE_SEGMENT_DOT_SIZE as it's length. This
 effectively fixes problem of rendering DOTS hats from DWF.
