This was the simplest one to start with. I need to add support for the "filter effect subregion" in order to handle tile stitching property, so this isn't quite complete. But I believe this is enough for the basic filters-turb-01-f test to pass, which gives us a baseline for further filter work. Summary of changes: - Added attribute type and parsing for SVG integer datatype - Added new node class for feTurbulence - Added several new properties and parsing for feTurbulence Bug: skia:10841 Change-Id: I8c877a5e1a837bfd527782253062eeb58febdde6 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/330621 Commit-Queue: Tyler Denniston <tdenniston@google.com> Reviewed-by: Florin Malita <fmalita@chromium.org>
