[PATCH 0/1] MR2537: include: Add windows.ui.core.idl file.

[Mohamad Al-Jaf (＠maljaf)]

Needed for mingw Firefox build.

It looks like CoreDispatcher was added as a forward declaration for `ICompositionObject`: https://searchfox.org/mozilla-central/source/taskcluster/scripts/misc/mingw-...

However, just having `interface ICoreDispatcher;` alone does not generate the IUnknown methods. I don't know if commenting out the functions is acceptable.

[PATCH 1/1] include: Add windows.ui.core.idl file.

I think it's best not to comment methods. They may be used to generate UUIDs, as part of the interface signature. If we need to add more types for that, so be it.

In this case it doesn't seem to bad, with just a couple of enums, delegates and a runtimeclass to add.
