ade110894d Fix borrow error when destroying an item during rendering 
Destroying a component releases the item's graphics resources, which requires
a mutable reference to the rendering cache. That reference is acquired fine grained,
but when rendering items itself we also acquired a mutable reference
at the start of the rendering phase. That is too early and too long, and not necessary.

56d763cdcf Implement GridLayout using stretch's FlexBox implementation 
Unfortunately nesting the boxes to model a grid does't seem to quite
work, so this approach simply creates two boxes for each direction --
similar to the existing algorithm.

9ad8968529 Add support for the initial_focus synthetic property 
Setting it will translate to a set_focus_item call in the constructor.

This implements parts of #55

3b6679ed4b Two ways binding works also work as three ways binding and more 
A side effect is that the order of calling set_binding and link_two_ways is no longer relevant

60cf022b69 Fix the two ways binding being flacky in the interpreter 
The two way binding must be set at the end.
It is flacky because the order currently depends on the order in the Hashmap

e5dfb3a4c0 Implement basic focus handling 
Similar to the mouse_grabber, we use a VisitChildrenResult field to
track the focus item within a component. Unlike the mouse grabber
however, it is set/cleared using dedicated focus events.

The key event now routes the key event directly to the focus item.

The focus can be requested via set_focus_item on a window, which the
TextItem does.

aa5babffe1 Prepare for key event delivery to a specific focus item 
Begin by routing key events through the component. In the future that
will direct the event to the focus item.

2b76e9277a Prepare for allowing an item mouse handler to request focus 
In the future the TextInput will request focus on mouse click,for
example.

Pass the outer-most component through to ItemVTable's input_event.

For the purpose of disambiguating this component from any nested
component instantiated by a repeater or so, it's called the
app_component.

The ComponentVTable takes a reference to a ComponentRefPin instead of a
ComponentRefPin by value, as the vtable macro gets confused otherwise
and thinks it's a self argument.

7ca66d62b9 Fix crash in TextInput when deleting a left-directed selection 
When selecting to the left, the anchor remains to the right of the cursor.
When deleting such a selection, we fetch the cursor and anchor using a helper
method, which ensures that the anchor is to the left of the cursor.
Finally when setting the cursor then to the anchor, we need to also
set the anchor, since both were swapped.

This also add an automated test for this scenario.

d70acce73f Prospective fix to remove wayland dependency 
Apparently wayland is pulled in by copypasta and a second time through winit.
Disable it from copypasta since the API isn't unified anyway:

There's no FooClipboardContext::new() for wayland, instead an unsafe function must be used to create the provider.
