Update to Bevy 0.13

[Jondolf]

Objective

Closes #314 and #317.

This PR will be merged once Bevy 0.13 is released. Feel free to use this bevy-main branch in the meantime if you want to use the main branch of Bevy with bevy_xpbd.

Solution

Update to the latest Bevy version.

For the 0.13 migration, I will be trying to implement various changes, mostly surrounding the new geometric primitives and ray structs. I will probably do these in PRs that I merge into this one, and it will all be merged into main once 0.13 is actually released.

• Combine PhysicsDebugRenderer and PhysicsDebugConfig into PhysicsGizmos gizmo configuration group
• Support creating colliders from primitives Colliders from primitives #326
• Support ellipses and regular polygons as colliders (conical frusta and tori later) Colliders from primitives #326
• Support creating ShapeCasters with primitive shapes
• Use Direction2d/Direction3d in spatial query APIs Use direction types in ray and shape casting APIs and add RayCaster::from_ray #329

Migration Guide

Debug rendering

The PhysicsDebugConfig resource and PhysicsDebugRenderer system parameter have been removed in favor of the new PhysicsGizmos gizmo configuration group.

Before:

fn main() {
    App::new()
        .add_plugins((
            DefaultPlugins,
            PhysicsPlugins::default(),
            PhysicsDebugPlugin::default(),
        ))
        // Configure physics debug rendering
        .insert_resource(PhysicsDebugConfig {
            aabb_color: Some(Color::WHITE),
            ..default()
        })
        .run();
}

After:

fn main() {
    App::new()
        .add_plugins((
            DefaultPlugins,
            PhysicsPlugins::default(),
            PhysicsDebugPlugin::default(),
        ))
        // Configure physics debug rendering
        .insert_gizmo_group(
            PhysicsGizmos {
                aabb_color: Some(Color::WHITE),
                ..default()
            },
            GizmoConfig::default(),
        )
        .run();
}

This also allows you to configure e.g. line width for just physics gizmos by configuring their GizmoConfig.

Renamed Collider constructors (#326)

• Replace Collider::ball with Collider::circle in 2D and Collider::sphere in 3D
• Replace Collider::cuboid with Collider::rectangle in 2D

Ray and shape casting (#329)

For spatial queries, replace Vec2/Vec3 directions with Direction2d/Direction3d.

// Before
let caster = RayCaster::new(Vec3::ZERO, Vec3::X);

// After
let caster = RayCaster::new(Vec3::ZERO, Direction3d::X);

This applies to RayCaster, ShapeCaster, SpatialQuery methods like cast_ray, and many other methods that use directions.
