# Objective
- for smallvec some crates specify default features false, other dont.
turns out we dont need them
## Solution
- remove
## Testing
- 3d_scene
# Objective
- Progress towards #19887.
## Solution
- Convert `FromWorld` impls into systems that run in `RenderStartup`.
- Move `UiPipeline` init to `build_ui_render` instead of doing it
separately in `finish`.
Note: I am making several of these systems pub so that users could order
their systems relative to them. This is to match the fact that these
types previously were FromWorld so users could initialize them.
## Testing
- Ran `ui_material`, `ui_texture_slice`, `box_shadow`, and `gradients`
examples and it still worked.
# Objective
Move Bevy UI's rendering into a dedicated crate.
Motivations:
* Allow the UI renderer to be used with other UI frameworks than
`bevy_ui`.
* Allow for using alternative renderers like Vello with `bevy_ui`.
* It's difficult for rendering contributors to make changes and
improvements to the UI renderer as it requires in-depth knowledge of the
UI implementation.
## Solution
Move the `render` and `ui_material` modules from `bevy_ui` into a new
crate `bevy_ui_render`.
## Testing
Important examples to check are `testbed_ui`, `testbed_full_ui`,
`ui_material`, `viewport_node` and `gradients`.
