* WIP: IME support for X11
* Handle text generated by IME.
* Set IME position according to the cursor position.
* Improve IME position handling.
Geometry as well as window focus changes are now handled.
* Dispatch IME strings like it's done on windows.
* Make sure not to silently drop IME errors.
* Respect `use_ime` configuration.
* Add xcb-util as dependency.
* Only update IME position if necessary.
* Formatting.
* Update xcb-imdkit-rs.
* Set IME position under the start of the cursor.
This seems to be the way it is commonly done among gui frameworks.
(Tested with Firefox for GTK and Konsole for QT).
* Update xcb-imdkit-rs.
* Handle systems only providing libxcb-util0-dev.
* Add libxcb to freebsd dependencies.
Required by xcb-imdkit-rs.
* Update xcb-imdkit-rs.
* Try to use more recent gcc on centos7.
* More recent C++ compiler on centos7 as well.
* Also setup correct env on centos7 for tests.
This replaces the slightly gnarly subpixel enabled blending in the
shader with Dual Source Blending, which is a technique where the
fragment shader can specify both the primary color (RGBA) as well
as an additional per-channel mask that can be used to alpha blend
with the destination.
This enables artifact-free alpha blending when used together
with a transparent window background.

Terminal now maintains a sequence number that increments
for each Action that is applied to it.
Changes to lines are tagged with the current sequence number.
This makes it a bit easier to reason about when an individual
line has changed relative to some point in "time"; the consumer
of the terminal can sample the current sequence number and then
can later determine which lines have changed since that point
in time.

Adds a use_image feature to termwiz that enables an optional
dep on the image crate. This in turn allows decoding of animation
formats (gif, apng) from file data, but more crucially, allows
modeling animation frames at the termwiz layer, which is a pre-req
for enabling kitty img protocol animation support.

Adding an edge from wezterm-ssh -> async_ossl causes the
openssl vendoring feature selection logic to trigger, which
in turn allows `cargo build -p window --examples` to succeed
again on macos.
0.8 doesn't seem to build with rusttls, but I don't think
we need that any more: we've been using vendored openssl on windows
and mac for some time.

The main culprit was the calloop feature that is used by default
in the underlying SCTK crate.
This commit:
* Routes keyboard processing via the same keyboard mapping code
that we use for X11
* Implements key repeats directly, and with awareness of elapsed
time in case the repeat rate is quicker than the event dispatching
quantum
* Disables the calloop feature of SCTK and let us do our own polling
of the wayland connection.
Critically, key repeat is sticky and unpredictable while calloop is
enabled.
