Have canvas drawImageFromRect just redirect to use drawImage

[Matthew Delaney]

Currently drawImageFromRect re-implements pretty much everything drawImage does already for it. It should just use drawImage directly instead.

This change looks unrelated. If you did intend to include it, then the changelog should describe it, and the testcase should exercise it.

Good call. I initially thought it would be best for drawImageFromRect to behave just as drawImage does WRT dom exceptions and such. Though, since it's simply a legacy routine used by only a few sites and dashboard widgets, I think it's best to leave its behavior as-is. Updated patch does so.
