Application.Slim.* packages only provide blocking Run() methods

[haraldsteinlechner]

Currently we have multiple options for creating windows etc:

• Aardvark.Application.WinForms which is net 47 based or
• Aardvark.Application.Slim which runs in netstandard

For usage in F# interactive setups it is necessary to open the window without blocking FSI. here is an example.

Unfortunately the netcore (Slim) variants only provide blocking Run() methods for windows making them unusable for interactive setups.

IMO, what we would need here is:

• window.Visible <- true methods for opening a window in a non-blocking manner
• maybe a mechanism to hook FSI's message loop. this might be a good starting point.

With net471 this is all possible via SimpleRenderWindow, but a contribution here could lift also interactive support to pure netcore level.
