SWF (Macromedia Flash) Input and Output Format.
SWF is a Vector Graphics Animation format, defined by MacroMedia, also known
as the Flash Format.
This package provides a low-level reader and writer for SWF files:
  - SWFInputStream to read .swf files
- SWFOutputStream to write .swf files
and an implementation of VectorGraphics:
The current implementation supports Version 3 of SWF.
SWF files can be imported by the following applications:
  - MacroMedia Flash plugin for Netscape and Internet Explorer
- Other MacroMedia products
In all these applications both online viewing and printing are supported.
The following Limitations exist:
  - TestShapes, no text, long blue horizontal lines.
- TestImages does not work.
- TestTransforms, lines too thick.
- TestTaggedString does not work.
- TestPrintColors strange.
- TestPaint no textures.
- TestLineStyles, line endings, line joins and dashing should be simulated.
 from the doc:
      - All lines in Macromedia Flash (SWF) have rounded joins and end-caps.
 Different join styles and end styles can be simulated with a very narrow
 shape that looks identical to the desired stroke.
- Macromedia Flash (SWF) has no native support for dashed or dotted line styles.
 A dashed line can be simulated by breaking up the path into a series of
 short lines.
