BREAKING CHANGE: gtk-layer-shell is now required and unconditionally
used. The corresponding config option is removed.
As a part of preparation for future versions of GTK, remove an ability
to use wlr-layer-shell directly. The APIs it required were dropped in
GTK4, and with the menus/tooltips positioning issue being practically
unsolvable it doesn't make sense to keep maintaining the code.
currently, the orientation of group modules is always the opposite of
the bar. Change it so that:
* the default orientation of the group module is always the opposite of
its parent, even for nested groups
* the orientation can be overridden in the config
* css ID and class are set for the group element
Don't set the anchor for certain edges when the width or the height
is not set to a value of 'auto' (1).
When the bar is vertical, the top and bottom edges are not anchored
otherwise the left and right edges are not anchored.
This resolves an issue wherein the width and height set for the
layer-shell were ignored because the layer was set to anchor to all
edges.
There is a double delete situation which causes a SIGSEGV to happen
during destruction of bar.
This was introduced by the group feature patch.
The same object pointer is stored in two different vectors of
unique_ptr<AModule> element. Replace with shared_ptr to handle
reference counting correctly and avoid double delete.
Allow changing existing modes and adding new ones via `modes`
configuration key.
`modes` accepts a JSON object roughly described by the following type
```typescript
type BarMode = {
layer: 'bottom' | 'top' | 'overlay';
exclusive: bool;
passthrough: bool;
visible: bool;
};
type BarModeList = {
[name: string]: BarMode;
};
```
and will be merged with the default modes defined in `bar.cpp`.
Note that with absence of other ways to set mode, only those defined in
the `sway-bar(5)`[1] documentation could be used right now.

I was seeing "[warning] Requested height: 20 exceeds the minimum height: 30 required..."
Lines 114-134 are relevant; 133 overrides the requested height with the minimum height when GTK wants more pixels to work with. So, the code is behaving as expected, and "less than" matches the code's logic.
This is very useful when writing CSS that affects more than just a
single widget. Pass `-l debug` to enable debug logging and show this
information.

Invisible bar on a `top` layer would still intercept pointer events and
stop them from reaching windows below. Always changing the layer to
to `bottom` along with making bar invisible would prevent that.
Extract two surface implementations from the bar class: GLSSurfaceImpl
and RawSurfaceImpl. This change allowed to remove _all_ surface type
conditionals and significantly simplify the Bar code.
The change also applies PImpl pattern to the Bar, allowing to remove
some headers and fields from `bar.hpp`.
Previous attempts to use auto exclusive zone from gtk-layer-shell failed
because gls was expecting real booleans (`TRUE`/`FALSE`) as set_anchor
arguments. With that being fixed, gtk_layer_auto_exclusive_zone_enable
makes gls handle everything related to the bar resizing.
The only remaining purpose of onConfigureGLS is to log warnings and bar
size changes; gtk-layer-shell code path no longer needs saved width_ or
height_ values.
Read `layer`, `exclusive`, `passthrough` into a special mode "default".
Drop `overlay` layer hacks, as it's easier to use `"mode": "overlay"`
for the same result.
Use `mode` (`waybar::Bar::setMode`) as a shorthand to configure bar
visibility, layer, exclusive zones and input event handling in the same
way as `swaybar` does.
See `sway-bar(5)` for a description of available modes.
