This is only exposed when internal types are exposed (such as in the lsp).
The plan is to make this public under a new name/global after the release.

Although std-widgets provides many properties that adapt to the current theme users who would like to go beyond these properties and do theme dependent changes are limited. One option would be to add even more properties to the Palette, however this would potentially bloat the object, it's not obvious what properties users care about and this approach doesn't scale. In many cases developers could simply create their own properties if they knew what the current runtime theme was.
This simple change allows an app to know what the current theme is and present theme appropriate UI's.
Instead of having all style duplicated and re-using a base, we just hack
into the funciton that queries the dark/light theme based on the style
suffix known at compile time.
This removes one of the problem that happens when trying to work on the
widget style with the extension, as it relies on include path hacks
Updated the version from 1.1 to 1.2
Renamed the header to "Slint Royalty-free Desktop, Mobile, and Web Applications License"
Added definition of "Mobile Application" and grant of right
Moved "Limitations" to 3rd section and "License Conditions - Attributions" to 2nd section
Added flexibility to choose between showing "MadeWithSlint" as a dialog/splash screen or on a public webpage
Moved the para on copyright notices to section under "Limitations"
The widget should not reach into the NativeStyleMetrics directly,
it should get the information from the StyleMetrics which return
the right value (which is not dark style, for the fluent style)
Add flags that enable the Button to be used as a Toggle, e.g. for use in toolbars or similar places.

Implement basic accessibility (a11y) support, using the Qt backend.
_This should get us started, but accessibility support is an additional way to interact with UIs that is very different from the "graphical way" most users will interact with the UI. No single PR will "make a toolkit accessibility", this needs to be an ongoing effort!_
Parts of this PR:
* Add functions to access a11y-related properties to Component
* Add helper functions to Item struct
* Handle accessible- properties in the compiler
* Add documentation, add description, enforce some basic rules
* Make the Text element accessible by default
* Don't optimize away accessibility property in the LLR
* Ensure that accessibility property are marked as used
* Add some accessibility properties to the native style widgets
* Support for bool and integer `accessible` properties
* Implement basic support for accessibility
* Make basic widgets accessible by default
* Make slider focus-able and interactable with keyboard
* Tell a11y layer about value changes
* Generate QAccessible constants using bindgen
* Don't expose the `accessible` properties when using the MCU backend: There is no backend to make use of them
* Handle focus change based on keyboard focus of the window
* Report accessible widgets at correct positions
* Allow for (virtual) focus delegation at the a11y level
* Calculate value step size dynamically
* Make sure to not send notifications to a11y backend about dead objects
