Detailed Description

Developer-facing API for rendering anything within the engine.

|DlCanvas| should be used to render anything in the framework classes (i.e. lib/ui), flow and flow layers, embedders, shell, and elsewhere.

The only state carried by implementations of this interface are the clip and transform which are saved and restored by the |save|, |saveLayer|, and |restore| calls.

Note

The interface resembles closely the familiar |SkCanvas| interface used throughout the engine.
