Import animated SVG files into Friction v1

[pgilfernandez]

Continuing with AI and the idea of importing/exporting new animation file formats, I would find importing "baked" SMIL animated SVGs into Friction so that users could edit them and convert them again into SVGs.

Here are the list of features:

• Added support for importing animated SVG files into a regular Friction project.
• Added a new Import SVG Animation action in the File menu.
• Added an import dialog that compares the SVG file with the active Friction scene.
• Added import options for scaling:
  • No scaling
  • Fit width proportionally
  • Fit height proportionally
  • Stretch to scene size
• Added import options for scene duration:
  • Keep the current scene duration
  • Extend the scene if needed
  • Fit the scene duration to the imported SVG
• Added grouped and ungrouped import modes.
• Imported SVG content as editable Friction objects when possible.
• Added support for animated SVG geometry.
• Added support for animated paint properties such as fill, stroke, and opacity.
• Added support for animated transforms, including translate, scale, rotate, and skew.
• Preserved imported SVG text styling.
• Added support for SVG image elements as linked image layers.
• Added support for dashed strokes and SVG dash patterns through Friction path effects.
• Added support for SVG masks as compositing layers.
• Added support for SVG group blend modes.
• Promoted SVG groups that need compositing into Friction layers.
• Expanded repeating SVG animation tracks into Friction animation keys.
• Added support for SVG animation timing, key values, and spline interpolation.
• Unsupported SVG animations are reported in the import dialog and skipped safely.

It makes sense to adapt this code to the Friction v1.1 plug-in system, I'm just dropping it here so that we can experiment with it. 😉
