* Base class for sources that start out as textures. Optionally allows for a content area subrect.
* The intent is not to use content area for subrect rendering. Rather, the pixels outside the
* content area have undefined values and shouldn't be read *regardless* of filtering mode or
* the SkCanvas::SrcRectConstraint used for subrect draws.
