-//  !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-//
-//  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.
