// Canvas is a PaintCanvas wrapper that provides a number of methods for
// common operations used throughout an application built using ui/gfx.
//
// All methods that take integer arguments (as is used throughout views)
// end with Int. If you need to use methods provided by PaintCanvas, you'll
// need to do a conversion. In particular you'll need to use |SkIntToScalar()|,
// or if converting from a scalar to an integer |SkScalarRound()|.
//
// A handful of methods in this class are overloaded providing an additional
// argument of type SkBlendMode. SkBlendMode specifies how the
// source and destination colors are combined. Unless otherwise specified,
// the variant that does not take a SkBlendMode uses a transfer mode
// of kSrcOver_Mode.
