Surface Error Fault Tolerance

[eblack-leaf]

Description
Program crashes after suspending program due to panic in Surface::get_current_texture.

Repro steps
git clone https://github.com/eblack-leaf/foliage.git
cd foliage
cargo run application

then suspend and reawake.

Expected vs observed behavior
I expect the Surface::get_current_texture to return Error using

if let Ok(surface_texture) = surface.get_current_texture() {
// use to render
} else {
// skip render
}

to skip rendering when suspended because no device can be reached.
It crashes in the call to get_current_texture instead of letting the
error branch run to avoid rendering.

Extra materials
Error Output after waking from suspend.
