[PATCH v9 0/2] MR2875: shell32: add support for balloon icon copying
Currently shell32 only transfers the plain icon for `Shell_NotifyIcon` calls, ignoring balloon icons. This patch allows transferring both images to explorer.exe tray. -- v9: shell32: add support for balloon icon copying shell32: refactor notify_icon to allow copying multiple icons https://gitlab.winehq.org/wine/wine/-/merge_requests/2875

I did this, because image data follows right after the struct, so I thought it's a bad idea to add two similar fields for two different images and stack two image bitmaps one after another straight away.
Also here the struct becomes smaller if there are no images present. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2875#note_82172

Otherwise it looks like an array of `notify_data_icon` although each struct is also variable sized.

Judging by functions looks like it isn't, it's attached to a module (HINSTANCE/HMODULE), not sure though why WINAPI chose HICON instead of plain HBITMAP object (maybe due to the mask layer being required). So I doubt that they would share the memory region (especially that small) to explorer.exe, so the icon could be displayed in systray.
