// SkNoDrawCanvas is a helper for SkCanvas subclasses which do not need to
// actually rasterize (e.g., analysis of the draw calls).
//
// It provides the following simplifications:
//
// * not backed by any device/pixels
// * conservative clipping (clipping calls only use rectangles)

Expose resetForNextPicture in SkNoDrawCanvas SkRecorder has some private Skia behavior with the way it handles an SkNoDrawCanvas that is not exposed. In particular, it's able to create an arbitrary SkIRect device clip at construction time. This is a performance optimization when reusing SkNoDrawCanvas across multiple recordings instead of reconstructing a new canvas every time. https://codereview.chromium.org/2768143002 is trying to implement another version of SkPictureBuilder/SkRecorder and so wants to be able to use similar SkNoDrawCanvas behavior.

Reland "Reland "Update SkCanvas' experimental SkiaRenderer API"" This reverts commit 138a06d1b1cd035daf6b6a970c75126e94777822. Reason for revert: add explicit constructors to ImageSetEntry to account for the new arguments, matching SkiaRenderer's current initializer list. Also hardens SkPictureDrawback's deserialization code for drawEdgeAAImageSet and drawEdgeAAQuad from a fuzz that was found during the CL's brief lifespan.
