This is the beginning of the bulk of de-skia-fication work in the engine. All of the standard types in the DlCanvas API now have overloads that specify the corresponding Dl type, mainly for Dl*Rect and DlPoint types. This enables further work to switch from SkFoo types to DlFoo types in the various engine modules culminating in the elimination of the old methods that use the Sk types. All of the former methods that used the basic Sk types are now implemented as inlinable translation overloads and the underlying implementations of DlCanvas now implement only the newer style interfaces so that they don't need to be further modified as we eliminate the old Skia types from the interface. There are still a couple of Skia types remaining in the DlCanvas API without any DL type variants which will be handled in a future phase: - SkRRect - SkRSXform - SkTextBlob (will be hidden behind a common interface along with TextFrame) - SkImageInfo (only used in a few calling sites)
Flow
Flow is a simple compositor based on Skia that the Flutter engine uses to cache recorded paint commands and pixels generated from those recordings. Flow runs on the raster thread and uploads information to Skia.
