Description Kimmo Kinnunen 2023-11-01 02:28:11 PDT 
CanvasRenderingContext::clearAccumulatedDirtyRect is redundant

Instead, the dirty rect should be cleared during buffer swap operation.
Canvas 2DContext should clear the dirty rect when it is indicated that the drawing buffer should be swapped to display buffer.
