Refactor the platform canvas unit test a bit so that it can be run on
multiple platforms. Also adjusts platfom_canvas.h and platform_device.h
so that some upper layers can include them instead of the windows
versions.
Change was originally http://codereview.chromium.org/1616, which was created in the wrong source tree. Applying approval from that issue.
