Description Andreas Kling 2010-07-17 23:13:36 PDT
GraphicsContext::fillPath() and GraphicsContext::strokePath() currently deep-copy m_data->currentPath before filling/stroking with it.

Since m_data->currentPath is cleared at the end of these functions, it's perfectly safe to fill/stroke using m_data->currentPath instead of a copy.
