dataphract 5bb4201f2e add informative panic message when adding render commands to a DrawFunctions that does not exist (#3924) ... # Objective If a user attempts to `.add_render_command::<P, C>()` on a world that does not contain `DrawFunctions<P>`, the engine panics with a generic `Option::unwrap` message: ``` thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', /[redacted]/bevy/crates/bevy_render/src/render_phase/draw.rs:318:76 ``` ## Solution This PR adds a panic message describing the problem: ``` thread 'main' panicked at 'DrawFunctions<outline::MeshStencil> must be added to the world as a resource before adding render commands to it', /[redacted]/bevy/crates/bevy_render/src/render_phase/draw.rs:322:17 ```		2022-02-13 00:14:37 +00:00
