-/** \class SkTrackDevice
- *
- *   A Track Device is used to track the callstack of an operation that affected some pixels.
- *   It can be used with SampleApp to investigate bugs (CL not checked in yet).
- *
- *   every drawFoo is implemented as such:
- *      before();   // - collects state of interesting pixels
- *      INHERITED::drawFoo(...);
- *      after();  // - checks if pixels of interest, and issue a breakpoint.
- *

-// TODO: can this be derived from SkBaseDevice instead?
