This adds single-symbol compose support using libxkbcommon's compose
functionality. E.g., assuming you have the right alt key defined as
your compose key, typing <RAlt>+i+' will produce í, and <RAlt>+y+= will
produce ¥. This makes compose key work for weston-editor,
weston-terminal, weston-eventdemo, and any other clients that use
Weston's window.* routines for accepting and managing keyboard input.
Compose sequences are loaded from the system's standard tables. As
well, libxkbcommon will transparently load custom sequences from the
user's ~/.XCompose file.
Note that due to limitations in toytoolkit's key handler interface, only
compose sequences resulting in single symbols are supported. While
libxkbcommon supports multi-symbol compose strings, support for passing
text buffers to Weston clients is left as future work.
This largely obviates the need for the weston-simple-im input method
client, which had provided a very limited compose functionality that was
only available in clients implementing the zwp_input_method protocol,
and with no mechanism to load system or user-specified compose keys.
