output: handle outputs that are enabled but not yet added
output_config_apply() currently assumes that any enabled outputs have

wlroots will report that outputs are enabled if they were previously in

output: auto-select mode when enabling output by client request
If e.g. kanshi requests us to enable an output but does not specify the
mode, and the output has not previously been modeset, then the width +
height + refresh rate will all be zero. In this case, we should select
the best mode just as when auto-configuring a new output.
We need to do the mode auto-selection in both the test & commit stages
for consistency, so factor out a new output_test_auto() function to help
with this.
Remove a guard against a refresh rate of zero, which was a workaround
for wlroots 0.17 and is no longer needed -- it is incompatible with mode
auto-selection since the refresh rate is zero in that case.

Remove cruft related to window switcher and keyboard focus
This commit cleans up the comments and cruft from e45fe08.
Background:
- With e45fe08, the keyboard focus is always moved to the switched window
on finishing window switcher, even with <focus followMouse="yes">.
Since followMouseRequiresMovement was not implemented at that time
(behaved like it was always "no"), e45fe08 was necessary to allow users
users who use followMouse="yes" to move the keyboard focus with window
switcher.
- 9a9e20d added followMouseRequiresMovement, but it kept the behavior
described above even with followMouse="yes" and
followMouseRequiresMovement="no".
- 398b80b accidentally invalidated e45fe08, which means the keyboard focus
is now always moved to the window below the cursor on finishing window
switcher with followMouse="yes" and followMouseRequiresMovement="no".
Although the invalidation was a accident, I think always setting the
keyboard focus on the window below the cursor is what users expect from
followMouse="yes" and followMouseRequiresMovement="no".

Clear keyboard/pointer focus on Move/Resize, window switcher and menu
The previous revert fixed the problem of stuck modifier keys with
keybinds in Blender, but made Firefox show its menu bar with Alt-*
keybinds. This is fundamentally inevitable due to the limitation of
wayland protocol, but at least for the default Alt-Tab keybind for
window switcher, we can mitigate this problem by clearing the keyboard
focus when the window switcher is activated. This is what KWin does, and
we decided to follow that.
So in this commit, keyboard and pointer focus are temporarily cleared
while Move/Resize, window switcher and menu interactions and restored
after them. We slightly deviate from KWin as KWin doesn't clear the
keyboard focus while Move/Resize, but it solves our existing problem
that Firefox shows its menu bar after dragging it with default Alt-Drag
mousebind, and this is what Mutter does.
We considered other solutions, but they don't work well:
1. Send wl_keyboard.{leave,enter} every time keybinds/mousebinds are
triggered. This solves the Firefox's menu bar problem, but that
sounds like a workaround and sending unnecessary events every time is
not desirable.
2. Send release events for both modifiers and keys even when they are
bound to keybinds. This is what Mutter is doing, but it looks like an
implementation issue and violates wayland protocol.

ssd: rework titlebar button rendering
- fix that icons for normal/hovered/rounded buttons are not placed
exactly the same position
- fix blurry window button icons in scaled outputs
This commit introduces lab_img and scaled_img_buffer and uses them for
rendering icons in the window titlebar. Now the process of rendering
button icons are split into 2 phases: loading with lab_img_load() and
creating scene-nodes for them with scaled_img_buffer_create(). This
might incur some additional overhead since we no longer preload icon
textures, but the rendering of icon only happens for the first window
as backing buffers are shared and the overhead won't be noticeable.
This commit also simplifies the process of centering icon buffer in the
button, by creating icon buffers in a fixed geometry via
lab_img_render().
