- Fix pre-processor include search path setup so that pre-processing
slint.h finds slint_internal.h and (most importantly)
slint_generated_public.h for the feature defines.
- Add missing documentation that caused doxygen errors.
Copying the Rust enum instead of using cbindgen because we would need to
create a new header just for it for bublic types generated in the
platform namespace. I've also put it in the SoftwareRenderer class since
the equivalent enum is in the software_renderer module in Rust.
- Don't try to create a GLX context when we only have an XCB window handle,
XLib is required for that.
- Make it possible to create a NativeWindowHandle from Xlib data types.
Fixes#2978
In Rust, register_component in the run-time library is called unconditionally and
invokes init(). The window adapter is an optional
parameter.
In C++, we'd call register_component only if we had a window adapter, which meant
that we're missing init calls().
