Bug 184336

The state of the drawing context has to be transfered to the recording DisplayList before recording. Many recording GraphicsContext functions will behave wrongly if get the default state. Here is a scenario of the bug: -- context.m_state.fillColor = RED (context is the underlying GraphicsContext for the recorded DisplayList) -- displayListRecorder is created to start recording. -- displayListRecorder.m_stateStack[0].lastDrawingState.fillColor = BALCK (Because lastDrawingState was initialized by the default GraphicsContextState) -- displayListContext is created which encapsulates the displayListRecorder -- displayListContext.setFillColor(BALCK) is called -- displayListContext.fillRect(rect) is called -- displayListRecorder is replayed back into context Result: -- displayListContext.fillRect() will end up calling Recorder::willAppendItem() which will call GraphicsContextStateChange::changesFromState() -- GraphicsContextStateChange::changesFromState() will not find a change in the fillColor. The recording GraphicsContext has it BALCK and it was BALCK. So there is no change here and the flag FillColorChange will not be returned -- Recorder::willAppendItem() will not append a new SetState item in the DisplayList -- The rectangle is filled with the current fillColor which is RED instead of BALCK as the caller wanted
