Does this have to be refcounted? Since this is all new code, maybe you can get
away with stricter ownership semantics?

[piman, 2016/02/24 01:52:13]

Agreed, let's do without at least at first, we don't have to follow the GL
semantics. In particular I suspect we'll want to bake in the synchronization /
ownership semantics which will probably look different than a simple refcount -
assuming this is intended to wrap the VkSurfaceKHR and/or the VkSwapchainKHR.

Done.
