> Follow up to #11600 and #10588 @mockersf expressed some [valid concerns](https://github.com/bevyengine/bevy/pull/11600#issuecomment-1932796498) about the current system this PR attempts to fix: The `ComputedTextureSlices` reacts to asset change in both `bevy_sprite` and `bevy_ui`, meaning that if the `ImageScaleMode` is inserted by default in the bundles, we will iterate through most 2d items every time an asset is updated. # Solution - `ImageScaleMode` only has two variants: `Sliced` and `Tiled`. I removed the `Stretched` default - `ImageScaleMode` is no longer part of any bundle, but the relevant bundles explain that this additional component can be inserted This way, the *absence* of `ImageScaleMode` means the image will be stretched, and its *presence* will include the entity to the various slicing systems Optional components in bundles would make this more straigthfoward # Additional work Should I add new bundles with the `ImageScaleMode` component ?
