Update to 1.1.1:

- When path clipping changes a LINETO to a MOVETO, it also changes
  any CLOSEPOLY command to a LINETO to the initial point. This fixes
  a problem with pdf and svg where the CLOSEPOLY would then draw a
  line to the latest MOVETO position instead of the intended initial
  position. - JKS

- The radius labels in polar plots no longer use a fixed padding,
  but use a different alignment depending on the quadrant they are
  in.  This fixes numerical problems when (rmax - rmin) gets too
  small. - MGD
