Mike Klein 7b093b7742 remove SkDebugCanvas clip query overrides
We don't think these are important, and it's looking
like overriding these methods at all is a bad idea.

While here we can remove kVizImageHeight and width too, as they're
unused.  After all these deletions the comment about methods inherited
from SkCanvas no longer applies.
