use precomputed border values (#15163) 
# Objective

Fixes #15142

## Solution

* Moved all the UI border geometry calculations that were scattered
through the UI extraction functions into `ui_layout_system`.
* Added a `border: BorderRect` field to `Node` to store the border size
computed by `ui_layout_system`.
* Use the border values returned from Taffy rather than calculate them
ourselves during extraction.
* Removed the `logical_rect` and `physical_rect` methods from `Node` the
descriptions and namings are deceptive, it's better to create the rects
manually instead.
* Added a method `outline_radius` to `Node` that calculates the border
radius of outlines.
* For border values `ExtractedUiNode` takes `BorderRect` and
`ResolvedBorderRadius` now instead of raw `[f32; 4]` values and converts
them in `prepare_uinodes`.
* Removed some unnecessary scaling and clamping of border values
(#15142).
* Added a `BorderRect::ZERO` constant.
* Added an `outlined_node_size` method to `Node`.

## Testing

Added some non-uniform borders to the border example. Everything seems
to be in order:

## Migration Guide

The `logical_rect` and `physical_rect` methods have been removed from
`Node`. Use `Rect::from_center_size` with the translation and node size
instead.

The types of the fields border and border_radius of `ExtractedUiNode`
have been changed to `BorderRect` and `ResolvedBorderRadius`
respectively.

Fix bevy_ui compile error when bevy_picking feature is disabled (#15053) 
# Objective

#14957 added the `pick_rounded_rect` function to `bevy_ui` in the
`picking_backend` module, which is gated behind the `bevy_picking`
feature. This function is used in that module, as well as in the `focus`
module. The latter usage is not gated behind the `bevy_picking` feature,
causing a compile error when the feature is disabled.

## Solution

Move the `pick_rounded_rect` function out of the `picking_backend`
module, as it does not depend on anything defined in that module. I put
it in `lib.rs` but it could reasonably be moved somewhere else instead.

## Testing

Encountered this compile error in a project and confirmed that this
patch fixes it.

Ignore clicks on uinodes outside of rounded corners (#14957) 
# Objective

Fixes #14941

## Solution
1. Add a `resolved_border_radius` field to `Node` to hold the resolved
border radius values.
2. Remove the border radius calculations from the UI's extraction
functions.
4. Compute the border radius during UI relayouts in `ui_layout_system`
and store them in `Node`.
5. New `pick_rounded_rect` function based on the border radius SDF from
`ui.wgsl`.
6. Use `pick_rounded_rect` in `focus` and `picking_backend` to check if
the pointer is hovering UI nodes with rounded corners.

## Showcase

```
cargo run --example button
```

## Testing

Modified button example with buttons with different corner radius:

```

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        // Only run the app when there is user input. This will significantly reduce CPU/GPU use.
        .insert_resource(WinitSettings::desktop_app())
        .add_systems(Startup, setup)
        .add_systems(Update, button_system)
        .run();
}

const NORMAL_BUTTON: Color = Color::srgb(0.15, 0.15, 0.15);
const HOVERED_BUTTON: Color = Color::srgb(0.25, 0.25, 0.25);
const PRESSED_BUTTON: Color = Color::srgb(0.35, 0.75, 0.35);

    >,
    mut text_query: Query<&mut Text>,
) {
    for (interaction, mut color, mut border_color, children) in &mut interaction_query {
        let mut text = text_query.get_mut(children[0]).unwrap();

hooking up observers and clicking for ui node (#14695) 
Makes the newly merged picking usable for UI elements. 

currently it both triggers the events, as well as sends them as throught
commands.trigger_targets. We should probably figure out if this is
needed for them all.

# Objective

Hooks up obserers and picking for a very simple example

## Solution

upstreamed the UI picking backend from bevy_mod_picking

## Testing

tested with the new example picking/simple_picking.rs
