Expand description

Generates SVGFEFilterInstances from a single SVGFEFilterTask, this is what prepares vertex data for the shader, and adds it to the appropriate batch.

The interesting parts of the handling of SVG filters are:

  • scene_building.rs : wrap_prim_with_filters
  • picture.rs : get_coverage_svgfe
  • render_task.rs : new_svg_filter_graph
  • render_target.rs : add_svg_filter_node_instances (you are here)
