// Adding new classes to Init() below has security consequences in Chrome.
//
// In particular, it is important that we don't create code paths that
// deserialize untrusted data as SkImageFilters; SkImageFilters are sent from
// Chrome renderers (untrusted) to the main (trusted) process.
//
// If you add a new SkImageFilter here _or_ other effect that can be part of
// an SkImageFilter, it's a good idea to have chrome-security@google.com sign
// off on the CL, and at minimum extend SampleFilterFuzz.cpp to fuzz it.
//
// SkPictures are untrusted data. Please be extremely careful not to allow
// SkPictures created in a Chrome renderer to be deserialized in the main process.
