Struct SharedGpu
pub struct SharedGpu {
pub device: Device,
pub queue: Queue,
}Expand description
Handles to the process-wide shared wgpu device — the very same one
every OffscreenRenderer draws through.
Apps that run their own GPU work headlessly (the video editor
composites its timeline frames with a wgpu compute pipeline) must
borrow these rather than stand up a second wgpu::Instance: parallel
vkCreateInstance calls race and SIGSEGV on several Mesa drivers,
which is the whole reason the shared context exists.
Both handles are Arc-backed inside wgpu, so cloning them out of the
context is cheap and they stay valid once the lock is released.

Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
