This test covers some basic cases, such as drawing the complete window to a canvas of the same size, drawing a part of the window to a different offset within the canvas, drawing parts of the window against different backgrounds and against a transparent background, and doing multiple such drawWindow calls on the same canvas. It runs its tests both with an iframe (whose background is transparent) and content in a new window (which has a white backdrop). Bug 995721 will add further tests (in mochitest-chrome) that exercise drawWindow from a toplevel chrome window, which exercises the DRAWWINDOW_USE_WIDGET_LAYERS codepath, which these tests do not. The final 4 tests in each set of 7 fail without patch 2 in this bug.
