Reduce or Eliminate dependencies

[Fweeb]

Currently, Swiffle requires installing a few non-stock Python modules (at least, non-stock in terms of what's shipped with Blender). Three of these are requirements of the PYSWF library that we've pulled into the add-on:

• six
• lxml
• pylzma

The fourth is Pillow, and that's used to help convert embedded image data in SWF files to Blender's internal image buffer.

Currently, we have an additional operator in the add-on to help users install those modules so Blender's Python can see them. It works, but it's not ideal. Choices at this point are either to also pull those modules into the add-on (making it a bigger download) or try to implement the parts that we need without actually using them.

All of this sounds like an awful lot of work...

Is there a manual way on recent Blender versions?
