[PATCH 0/1] MR9798: wined3d: Update the context DC from its swapchain if it changed.
The context keeps a weak pointer to the swapchain, and the swapchain might be destroyed while are context still have a pointer to them. It's usually not causing issues because contexts will be refreshed with the new active swapchain before a present is executed. However, the new swapchain might be for the same window but might have a different DC. As we now borrow the DCs from the swapchains, we also need to check if the context DC needs to be updated.
