For fonts like Lucida Console on Windows which do not have a bold
variant, we were not synthesizing bold.
The reason was that the config-level "make bold" logic works by adding
200 to the weight which takes normal -> demibold, but the bold synthesis
logic is enabled only for bold and higher.
This commit changes the threshold for synthesis to demibold or higher.

The hope here is that the nvidia-specific resize issue might have
a workaround if it is emitting some other events that we were
previously not listening for.
This commit optionally enables the Present extension and listens
for its version of CONFIGURE_NOTIFY, routing it through the same
logic as the base CONFIGURE_NOTIFY event.
On my AMD hardware under Gnome, I see something like:
```
18:04:26.476 TRACE window::os::x11::window > Present::ConfigureNotify: width 1168 -> 1180, height 858 -> 873, dpi 124.7998046875 -> 124.7998046875
18:04:26.478 TRACE window::os::x11::window > Ignoring X::ConfigureNotify (1180x873 dpi=124.7998046875) because width,height,dpi are unchanged
```
with the Present event firing before the X event.
Let's see how this goes.

I did an ad-hoc test where I set the new tab button background to
an Animated value and saw that it eased in and out.
However, this commit doesn't make anything use this yet.
Main idea here is to add expose events to the trace so that we
can get a sense of whether those are emitted when a WM isn't delivering
CONFIGURE_NOTIFY consistently.
If the exposed area is bigger than what we think the window is,
then we mark geometry as unsure.
I'm considering always marking as unsure for an expose event,
or at least, adding a config option to enable that, as a way
to workaround this situation.

This is prep for future work where I'll be moving more of the main
monospace rendering into the box model code and factoring out
this aspect of animation.
Useful if you want to add smaller items to your background layers
every so often; you can specify the distance between them and make
it independent of the item height.
The color can have alpha and blend with other layers.
This is helpful if your image has fully transparent portions
and you want to explicitly place a color in there.
The `File` variant for background layers may now be an object
that specifes a speed factor. That factor is applied to the
animation frame durations in the loaded image, allowing the
playback rate to be adjusted.
Adjusts the background rendering logic so that we now allocate
a render layer for each defined background layer. This allows
their individual opacity value to multiple and blend together.
As part of this, I noticed that the big jpegs I was using could
take 400ms or more to load, so I added a basic cache to avoid
loading the same image multiple times around a config reload.
This adds some types that will enable richer background images.
* Can specify multiple layers
* Each layer can select from image files or gradient definitions
* Layers have additional properties to specify positioning, scaling,
tiling and whether they scroll with the viewport.
None of the additional properties are hooked up yet.
This commit allows for the SplitPane internal action to use the
pane id of an existing pane as the source of the pane to be added
in the new split target, rather than spawning a new command.
This can be used to move a pane from one tab to another, and is
analagous to tmux's `join-pane` command.
