Don't treat shorthand filters as errors on SVG content

Don't treat shorthand filters as errors on SVG content

We don't support filter shorthands yet, so we shouldn't treat them as
errors. Fix up the hasFilter() condition to also check if it's a filter
that we pretend we can handle.

Also straighten out the code-flow in applyFilterIfNecessary.
