<pre>Currently, some wayland compositors have their own screenshot and/or screencast
feature, such as weston. Others, such as gnome-shell, have an additional public
DBus API [1]. For KWin, a similar feature is in the works [2].
This situation is bad because it looks like application developers need to
write a separate implementation for their tools for every desktop shell /
environment. For the sake of simplicity, can you please add one API (probably
an extension to the wayland protocol) for all desktop environments?

Some notes:
* Taking screenshots and recording screencasts should be an optional feature.
* The wayland compositor should be able to decide (based on rules or user
decisions) whether to allow or deny the request. For this, applications need to
have a way to provide information about themselves (like application name and
icon) and why they want to take a screenshot/screencast.
* Applications must handle being denied to take a screenshot/screencast
* there should be a way to select regions of the screen(s) only. I don't care
whether this should be implemented on client or server (compositor) side.</pre>
