Feature request

Describe the solution you'd like
It'd be great if Refract should be targeted at a specific window rather than the entire desktop. This would make it easier to do things like depth editing in PhotoShop.

Describe alternatives you've considered
Currently Photoshop has to be maximized.

The shortest path to supporting this would probably be to add support for uWindowCapture in addition to the currently supported uDesktopDuplication. This article (translation required) says that this will be slower than uDesktopDuplication, but if the target window is a lot smaller than the desktop it could be decent.

This article was written when uWindowCapture was released. It is old information.
uWindowCapture now supports WinRT Windows.Graphics.Capture API. It works very fast. See this article for details.

WinRT Windows.Graphics.Capture API is not supported on legacy Windows. (Windows 10 1803 or later is required)
Currently, the only advantage of using uDesktopDuplication is that it works on legacy Windows. If you want to maintain compatibility, I recommend using uDesktopDuplication as is.
However, i suggest you switch libraries if the reason you choose uDesktopDuplication is that it is faster than uWindowCapture.

There are several libraries for Unity that support WinRT Windows.Graphics.Capture API.
uWindowCapture also supports some legacy capture APIs, so it is highly compatible, but it is larger.
If you don't care about compatibility, you can consider using a tiny library such as UnityGraphicsCapture.
