Reftest '== path-01.svg[accelerated] path-01-ref.svg[accelerated]' fails in hardware-accelerated mode on Windows 7 with ATI Mobility Radeon HD 4650.

This problem does not occur on a Windows XP VM.
There's nothing green or lime in path-01.svg. It's like it's leftover from some previous test.

Yes.  The canvases in this test framework are recycled, so I suspect that drawWindow is completely failing for this test, and what we are seeing is the output from a previous test.
Indeed a draw call is failing:

D2D DEBUG WARNING - A Draw call by a render target failed [88990001]. Tags [0, 0].

Investigating.
This patch fixes the case of a path with a single move and a close instruction.
