Similar to the parent commit, don't calculate the native_padding_* as a side-effect of calling
layout_info(), but calculate it property through a binding.
Setting the value of the native_padding_{left, right, top, bottom}
properties *during* the layout_info() call is too late, as the calling
compute_layout implementation has already queried for those properties.
Instead, this patch moves the padding calculation into a shared property
binding that's queried from bindings to the individual native_padding_*
properties and layout_info() just uses the properties, too.
Move the main match out into a separate helper function in GLFrame and
keep render_primitive to just be the loop. This will also make it easier
to implement the dynamic primitives later.
The native style typically allocates a texture for its surface, and if that
exceeds the size of the texture atlas, then we need to adjust instead
of crash.
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.
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.

Also revert the QStyle::State_Horizontal in the spinbox that should not have been part of the previous patch
Unfortunately something is wrong with the Qt style, it looks like the Qt style
does not respect the rect given for the sub components
Also Input is not handled yet.
