Support Drag and drop output

[toluschr]

Hi,

I've been meaning to port my terminal emulator program (targeting Xlib) to RGFW for some time now to take advantage of multi-platform support.

However, it seems the library does not support dragging from the window (i.e., drag and drop output), which is a core feature of my program.

Would you consider adding this functionality to RGFW? If so, I'd be happy to write the X11 backend. I just wouldn't know what you wanted the API to look like.

Best regards,

This has been something I've wanted to add for a while. It's quite a low priority at the moment as it will take a lot of time to figure out how to implement it across each platform.

This will probably be implemented after 2.0 is released. However currently I am working on some changes for how RGFW handles drag and drop. Such as having a enum for the format. This should be helpful for the future implementation of drag and drop output.
