Macos guiwidget

[geon]

I implemented the GuiWidget as discussed here: #100 . Not sure I got it right though.

The EventUserData objects are allocated. They should probably be freed at some point? I don't know how I would do that.

Hi! Sorry for the late answer!

Yes the EventUserData objects should be freed. For this, there's the deinit function implemented (currently as a no-op) in Events. It could probably be like:

pub fn deinit(self: *const T) void {
  const peer = self.peer; // each component has a peer, so you can use the 'peer' field.
  lib.internal.lasting_allocator.destroy(peer.data);
}

One side note: you should use lib.internal.lasting_allocator instead of lib.internal.scratch_allocator, as the scratch_allocator is intended more for very short allocations (like UTF-8/UTF-16 conversions).

No worries! We all have limited time.

I fixed the allocations and added the deinit implementation.
