Make `StaticResource` and `DynamicResource` automatically convert `Color`s to `ImmutableSolidColorBrush`es and add a `ColorToBrushConverter` for use by bindings.
To do this I made `GetResourceObservable` accept an optional conversion function.
`Changing_Resource_In_Templated_Parent_Should_Affect_Templated_Child` now fails because resource changed messages no longer traverse into templated children.
Instead of each control listening to its parent `ResourcesChanged` event, use the logical tree to propagate `ResourcesChanged` events:
- When attaching to the logical tree, piggyback on the `AttachedToLogicalTree` traversal
- At other times, propagate by calling `NotifyResourcesChanged`
Split resource nodes into two types:
- `IResourceHost` represents controls and `Application`
- `IResourceProvider` represents resource dictionaries and styles, these are owned by `IResourceHost`s
Dynamic resources are now always resolved from an `IResourceHost`: if an `IResourceProvider` doesn't have a host then a dynamic resource in the resource provider will not be resolved. Resource providers no longer have a `ResourcesChanged` event, instead they notify their `IResourceHost` owner of a resource change by calling the `NotifyHostedResourcesChanged` method.
Make sure the item we're selecting is within the requested range. Also refactored the unit tests to do a simple test on `SelectedIndices` instead of using `IsSelectedWithPartial` because both can't really be tested together using the old testing method.
And remove child selection when a `TreeViewItem` is un-expanded.
This is necessary because we don't get enough information about a materialized `TreeViewItem` to select it when materialized, so the `SelectionModel` and `TreeViewItem` selection state gets out of sync.
Make `SelectionModelChildrenRequestedEventArgs.Children` an observable, so that the we can react to the children collection object changing, as well as the children inside the collection changing.
Upstream issue: https://github.com/microsoft/microsoft-ui-xaml/issues/2404
This requires that a `<Transitions>` element is used to contain the transitions in XAML and a `new Transitions()` is used when assigning transitions from code.
