This changes the component containers away from using a "MAGIC" index in the
placeholder dynamic item tree node it creates. These are hard to
integrate across sub-components.
Use index numbers right after the index numbers used by repeaters and
"extend" the repeater offset by the number of component containers in
the sub-component. This way we can piggy-back on the forwarding of
repeaters.
This has one annoying side-effect: We do have indices in our item tree
that are out of range for a repeater. But I think that is acceptable
considering that we never materialize that array anyway.
Parents surch as Opacity, Clip, and co, used to steal the x and y
property of their children, making the property not what they ought to
be.
Now that we refactored recently the code so that geometry need not to be
always linked to a property of the same name, we can dissociate the x
and y property of these generated elements and their content so that the
actual "x" property of the former elementstay some value, despite its
relative item property is now 0.
Had to change a bit of code that was still assuming a literal "height"
or "width" or "y" or "x" property that no longer worked when the
geometry is dissociated from its property
Fix#1072
Layout code generates a lot of code and it may be beneficial not to
generate constraints if there is no constraints in that direction

No measurable changes in compilation time.
So it doesn't appear in the LLR and the C++ codegen can be simplified.
In particular, this removes the need to throw/catch exception to handle return
across generated lambdas
This patch adds a `close()` function that can be called to close a popup
window, and a `close-to-click` boolean that can be set to false to
disable the default behavior.
The added functions enable mixing colors and manipulating the opacity
of colors and brushes.
They enable the behavior of some of the available functions from SASS and are
added for future use for adding the Adwaita style (future PR).
In the compiler this is still very primitive, but an attempt to start a
generic interface. The basic assumption is that all item functions will
eventually need access to the window adapter and itemrc. Support for
additional arguments is still missing.
Also missing is support for the function access via rtti in the
interpreter, hence the hardcoding at the moment.
If one declare a `property <int> foo;` in Slint, it will be private by
default, and the getter/setter won't be generated, and it may be
confusing as to why
With this change, it still generate private getter and setter so this
gives a better hint to the developer what the problem is.
Replaces #2170
This type is poorly implemented and not documented. Let's remove it for now.
It shall remain available in the git history in the event of a resurrection.
These are two different concept, and it is confusing to keep them in the
same enum
We want to support component without any base element, and Void is
already used for global component, so do this refactoring before
