Description
This issue specifically tracks support for features required full support for CSS `filter()`. It does not track generalised SVG filter effect support.
## Tasks
- [x] Support the `GaussianBlur` filter primitive
- [x] Support the `DropShadow` filter primitive
- [ ] Support the `ColorMatrix` filter primitive
- [ ] Support the `ComponentTransfer` filter primitive
- [ ] Ignore unimplemented filter effects rather than panicking
- [ ] [cpu] Support setting the color in the `DropShadow` filter (already works in Hybrid)
- [ ] Support linear chains of filters
Bonus:
- [ ] Support filters in `vello_cpu`'s multithreaded mode

Research direction
Start by examining the existing GaussianBlur and DropShadow filter support, then compare the remaining tasks for ColorMatrix, ComponentTransfer, ignored effects, filter chains, and CPU DropShadow color handling. Check the vello_cpu Hybrid and multithreaded paths where relevant; done means the selected filter behavior works without panics and is covered by the project's existing validation.
