We're currently adding picture shader cache entries to the resource
cache, but we don't ever purge. To avoid exhausting the budget, add
logic to associate cached entries with their owning picture shader, and
purge when the shader is deleted.
-- Side note --
The current cache key is
K(pictureID, ...)
so technically the cache entries are associated with the picture, not the
shader. One could resonably argue we should only purge when the
*picture* is deleted. Unfortunately, this doesn't work: the cache entries
contain indirect refs to the picture (SkImageShader -> SkImage_Generated
-> SkPictureImageGenerator -> SkPicture), so the picture is always kept
alive.
Associating the cache entries with the shader itself seems like a
reasonable alternative, even if we give up some cache persistence in the
process.
