This check is not needed for GraphicsContextCG because all the callers check if (m_state.strokePattern) before calling this function. But it is needed for DisplayList::Recorder and RenderSVGResourcePattern::applyResource() because the callers do not check if (m_state.strokePattern) before calling this function. So I think we should either

1. Remove the check if (m_state.strokePattern) form GraphicsContextCG functions.
2. Remove this check and make DisplayList::Recorder and RenderSVGResourcePattern::applyResource() check if (m_state.strokePattern) before calling this function.

Ditto.
