Finish `WindowHandle` to `WinCtx` migration about druid HOT 3 CLOSED

file dialogs. These are trickier. It would be possible to just move the existing API over, but the idea of doing a blocking call to create a modal dialog from inside the window handler creates problems. A better API would be to request a file dialog (as a method on WinCtx), and pass in a closure which should be called on completion of the dialog. The implementation would then wait until control passes up from the window handler, and then do the blocking call from inside the shell, specifically, while not holding a mutable borrow on WindowState. This would let handlers run (eg for painting the window) while the modal dialog is up. It would also adapt much more easily to a non-modal dialog, which might be better UX.

I want to work on this one because I have a usage which is the same as the problem described in #115 which I want to fix.

It seems like WinCtx does't exist anymore, is this issue still valid?

you're right, this is outdated. thanks!
