Hello,

Here are some comments on the current filter specification,

Kind regards, Vincent

feCustomElement 
https://dvcs.w3.org/hg/FXTF/rawfile/tip/filters/publish/Filters.html#feCust
omElement

Except for feCustomElement, there is a predefined set of filters rather
than defining a language for filter processing. Ultimately, we think this
will limit usage and should indeed be augmented with a filter language.

Hit testing 
https://dvcs.w3.org/hg/FXTF/raw-file/tip/filters/publish/Filters.html#filte
rs-in-css 

The filter is defined to have no effect on hit testing when clicking into
the final rendered image. This is a concern: highly distorting filters
will basically create situations where the hit testing is completely at
odds with what the viewer sees. For example, in an extreme case, a filter
can blow away the image entirely, but it will still respond to hit
testing. Has the group discussed possible solutions to this problem?

Vincent.
