Previously, on Linux and BSD, inhibiting the screensaver was handled using the org.freedesktop.ScreenSaver D-Bus API. Unfortunately, this API is not available in a Flatpak sandbox. (This is because there is a desire to tie inhibit sessions to a specific app and visible window; but the org.freedesktop.ScreenSaver API does not support this.) As a result, when using the Flatpak build of the Godot Editor (or a Flatpak-ed build of a game) and using a controller to play a game, the session will become idle after a few minutes. The XDG desktop portal -- which is already used for color-picking, file choosing, and querying the system theme -- has an Inhibit interface that provides a superset of the functionality of the org.freedesktop.ScreenSaver API, and is available to any sandboxed app. Refactor code for making XDG portal requests that was previously duplicated for the FileChooser and ColorPicker portal code. Check the portal version to determine whether these portals can be used: - FileChooser portal version 3 is required due to the use of the "directory" parameter. - On the Settings portal, the only addition in version 2 is the ReadOne() method which is not used here, so version 1 suffices. - On the Screenshot portal, the only addition in version 2 is the "interactive" parameter to the Screenshot() method; this code only uses the PickColor() method, so version 1 suffices. Then, add support for the Inhibit portal. Use it if available and if running in a sandbox. Prefer to use org.freedesktop.ScreenSaver if not running in a sandbox, even if the portal is available, because (at least in the GNOME 43 implementation of the portal) it does not work correctly if the portal cannot map the request to a running app. This adds a small amount of complexity to the implementation, but supporting both APIs is necessary anyway (there are many systems in the wild that support org.freedesktop.ScreenSaver but not the desktop portal).
