Is it possible to theme the titlebars separately from the borders? i.e. when the title can be seen.

I'd like to create a windows 95 theme.

Hm, this sounds like an interesting idea. Not sure what the best way to implement it would be. Do you have any ideas regarding that, or even what the config command would look like?

No i don't have any ideas.

or even what the config command would look like?

Maybe the config could have an option of border_images..with_titlebar, and it would be an image with the same format as the other border images, but with longer top corners to match the height of the titlebar.

remove view from its own unmap event listener so when subsurfaces
link try to remove themselves they won't run into it.

This fixes the following ASAN use-after-free error on a build slightly

There seems to be a null pointer access that can happen. I was able to
reproduce this by running the cemu emulator[1] with the new collabora
wine wayland driver[2] and opening and closing some sub menus.

Adding a trival null check seems to do the trick to stop sway from
crashing and returning to tty and everything else works normally.
