Thanks for taking care of this, Jay.  I encourage everyone to take another read through the current ED [1] now that it has been reintegrated.  Rik has raised some concerns [2] which we can discuss on Monday.

> Hi All,
> Based on discussions from the Canvas Accessibility Sub-Group meeting on Monday 10 MAR 2014 [1], there was consensus that the version of the Hit Regions [2] spec I provided for review last week could be used as a base document for reintegration into the Level 1 spec with the following exceptions and notes:
> * Remove all mentions of and references to fillRule().
> * clearRect() should be the only method for clearing a region.  Adding a region that fully encompasses another region should not remove the encompassed region.  It should remain in case the encompassing region is removed (we should file a bug against WHAT WG regarding this as well).

> There was consideration of adding a glossary and/or other non-normative text to introduce parts of the specification that the purpose for may not be immediately obvious.  However, there was concern that the addition of lots of informative text would cause a noticeable deviation from the WHAT WG spec and would not be consistent with other parts of this spec.
> Unless there is disagreement with the above, I propose we move forward with reintegrating Hit Regions [1] back into the Canvas 2D Level 1 spec.  Bugs against the reintegrated text can be filed if additional issues are identified.
