On Windows we're seeing a max size = 0x0 swapchains. Those cannot be created or used. Make sure that we're not, and we're not trying to draw anything when there's no swapchain available. Unfortunately we still have to call some rendering functions (without actually rendering anything) to make sure that various invariants hold. fixes #463
