Freestyle: Built-in SVG exporter.

Features:
* Both still image and animation rendering, as well as polygon
  fills are supported.
* The exporter creates a new SVG layer for every Freestyle line
  set. The different layers are correctly sorted.
* SVG paths use data from line styles, so the base color of a
  line style becomes the color of paths, idem for dashes and
  stroke thickness.
* Strokes can be split at invisible parts.  This functionality is
  useful when exporting for instance dashed lines or line styles
  with a Blue Print shader
* The exporter can be used not only in the Parameter Editor mode,
  but also from within style modules written for the Python
  Scripting mode.
