           Summary: Possible error in canvas Philip test
           Product: HTML WG
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: LC1 HTML Canvas 2D Context (editor: Ian Hickson)
        AssignedTo: ian@hixie.ch
        ReportedBy: benwells@chromium.org

This test is checking that no zero length segments are removed when using arcTo
and arc. The code for checking arc is:

ctx.moveTo(50, 25);
ctx.arc(50, 25, 10, 0, 0, false);

I think this should create a line from (50, 25) to the start of the arc, which
in this case will be (60, 25): the center of the circle is (50, 25), the radius
is 10 and the start angle is 0.

I believe arc call should be changed to:
ctx.arc(40, 25, 10, 0, 0, false);
