Issues with the triangle example and vulkan on windows about rendy

[zakarumych]

It seems example holds on Surface object longer that it should.
It works otherwise. It is coded to shutdown in few seconds.

[trsh]

@omni-viral can this be fixed? Suggestions?

[zakarumych]

The fix is easy. One must destroy Surface before dropping Factory

[trsh]

@omni-viral why Im trying to study and understand the example code, could drop some lines how that surface drooping should be like. Or maybe update the example? Pls
Im trying to hack out the surface from graph, as its is moved into its node, but somehave stuck:

let s = graph.take().unwrap().nodes; // field `nodes` of struct `rendy_graph::graph::Graph` is private
            graph.take().unwrap().dispose(&mut factory, &());

[trsh]

Been looking all day long how to get to surface to destroy it with no luck. Any help appreciated

Happens for me on Linux with Vulkan as well

[trsh]

I think Rendy should handle the surface destroying before Factory, so this is a bug.

gfx_hal::Instance::destroy_surface is never called (I didn't find it in the whole repository).

rendy::Factory::destroy_surface just drops the surface without calling gfx_hal::Instance::destroy_surface. Is this by intention?
