Actionable objects (still a prototype) were outlined when you walk next to them.
The OutlinePipeline was broken when moving in Phaser 3.50+.
This PR completely removes the custom OutlinePipeline and replaces it with the rexOutlinePipelinePlugin
that is provided by a third party library and that works great \o/
Turning the "importsNotUsedAsValues" TS config value to "error".
This will require us to use `import type` instead of `import` when we are importing a value that is only used as a type (and therefore that is dropped by the Typescript compiler).
Why this change?
This is a requirement to be able to use Svelte in the future. See https://github.com/sveltejs/svelte-preprocess/issues/206#issuecomment-663193798
This code is broken since Phaser 3.50 and we are facing weird issues with MacOS memory leaks and crashes.
Removing this code will remove one potential suspect.
The switch to Phaser 3.50 introduced a bug when WebGL is not available in a browser.
The changes in this commit prevent calls to the WebGL pipeline if the pipeline is not available.
