add IME support

Based on mangowm, which is based on labwc, which is based on sway, so
this should be covered by LICENSE.sway.

+## Background
+
+dwl is not meant to provide every feature under the sun. Instead, like [dwm], it
+sticks to features which are necessary, simple, and straightforward to implement
+given the base on which it is built. Implemented default features are:
+
+- Any features provided by [dwm]/Xlib: simple window borders, tags, keybindings,
+  client rules, mouse move/resize. Providing a built-in status bar is an
+  exception to this goal, to avoid dependencies on font rendering and/or drawing
+  libraries when an external bar could work well.
+- Configurable multi-monitor layout support, including position and rotation
+- Configurable HiDPI/multi-DPI support
+- Idle-inhibit protocol which lets applications such as mpv disable idle
+  monitoring
+- Provide information to external status bars via stdout/stdin
+- Urgency hints via xdg-activate protocol
+- Support screen lockers via ext-session-lock-v1 protocol
+- Various Wayland protocols
+- XWayland support as provided by wlroots (can be enabled in `config.mk`)
+- Zero flickering - Wayland users naturally expect that "every frame is perfect"
+- Layer shell popups (used by Waybar)
+- Damage tracking provided by scenegraph API
+
+Given the Wayland architecture, dwl has to implement features from [dwm] **and**
+the xorg-server. Because of this, it is impossible to maintain the original
+project goal of 2000 SLOC and have a reasonably complete compositor with
+features comparable to [dwm]. However, this does not mean that the code will grow
+indiscriminately. We will try to keep the code as small as possible.
+
+Features under consideration (possibly as patches) are:
+
+- Protocols made trivial by wlroots
+
+Feature *non-goals* for the main codebase include:
+
+- Client-side decoration (any more than is necessary to tell the clients not to)
+- Client-initiated window management, such as move, resize, and close, which can
+  be done through the compositor
+- Animations and visual effects

+  <description summary="Control power management modes of outputs">
+    This protocol allows clients to control power management modes
+    of outputs that are currently part of the compositor space. The
+    intent is to allow special clients like desktop shells to power
+    down outputs when the system is idle.
+
+    To modify outputs not currently part of the compositor space see
+    wlr-output-management.
+
+    Warning! The protocol described in this file is experimental and
+    backward incompatible changes may be made. Backward compatible changes
+    may be added together with the corresponding interface version bump.
+    Backward incompatible changes are done by bumping the version number in
+    the protocol and interface names and resetting the interface version.
+    Once the protocol is to be declared stable, the 'z' prefix and the
+    version number in the protocol and interface names are removed and the
+    interface version number is reset.
