labwc: Replace waybar with ironbar

[humaidq-tii]

Replaces waybar with ironbar.

Ironbar is a replacement for waybar that is customisable, modular, and supports showing running applications on the taskbar.

Depends on: #582

Description of changes

• Replaced waybar with ironbar, preserving same style.
• Running applications now show on taskbar, can switch tasks.
• Added volume widget.
  • Ability to change master volume, and individual VMs volume.
• Align more with Figma designs.

Also other changes:

• Added window shadows
• Fixes wifi icon (used to show code when percentage <30)
• Launcher now opens instantly
• Volume media keyboard hotkeys now change volume instantly.

Known issues

• If too many windows are open, or with long window names, taskbar may go off screen (to the right).
• Sometimes when closing the launcher, the compositor won't update until you hover over it. Seems to only happen pixman (software-based) renderer.
• Moving audio slider doesn't change volume, but it does correctly update when using the volume media keys.
• Two taskbars are shown when an external display is connected.
• Battery icon in taskbar uses wrong theme (light theme, dark icon over dark panel).
• Battery icon shows on Orin (0% with question mark battery icon).

rebased to current tip of Ghaf main without conflicts: 4f2291c

platform: Lenovo X1 Carbon

• ci-test-automation suite: ok
• starting apps: ok

works:

• windows have border shadow
• switch apps from the taskbar (if they are visible and still running)
• app drawer
• clicking on wifi icon shows SSID & IP
• volume icon & handling works
• battery shows estimate (takes ~5 secs to update after plug/unplug)
• time/date mini calendar
• connect/disconnect external display
• long names are truncated on taskbar with ellipsis
• taskbar stays on screen

issues:

• wifi strength seems to have "full", "almost full", "none" and "else echo" values
  
• lower wifi strength values are not visible
• battery shows an empty bar when on charger, but probably not charging (96%)
  
  • or just "Full in"
    
• sometimes clicking on the settings cog-wheel doesn't open Network Settings, have to click again
• external display stays on and frozen when closing the lid
• app names are not centered on their taskbar "tile" (see previous image)
• apps can fall out of visibility on the taskbar (many open apps & long names)
  
• list of grouped apps on taskbar can stay on after doing something else somewhere else
  
  • they can stay there after all apps are closed
    
• in some cases the wrong (not the active) title is displayed on the taskbar for grouped apps
  • even the title of a closed app can stay visible (see previous 2 images)
• window content doesn't stay inside it's own border when resizing somewhat quickly

NVIDIA Jetson AGX Orin native, booted Orin AGX from eMMC
Check with commit: 7bbaf35

• automation cases: ok
• launching apps and manual regression tests: ok

Issues:

• When you open lots off browser windows, zathura- and windows vm-windows: some point the new zathura and window vm-windows counts don't increase in taskbar anymore.
  And finally the taskbar disappeared totally.
  Luckily you can open the window, where you can launch the terminal and reboot the ORIN from command line. After reboot the taskbar is available again.
  

taskbar.odt

• Battery icon is shown although there is now battery in Orin AGX
  

• When you tap in the taskbar left side of battery icon(no any visible icon in that point) the volume information comes visible:
  

• app names not centralized in task bar:
  

• list of grouped apps on taskbar stay open although you are doing else in the screen:
  

• You have for example three browser-window with different pages opened and the second pages in the list activated and visible in the taskbar

  1. when you tap the keyboard "print screen"-key, the third-page on the list comes visible on the taskbar, but the second page is still active on the screen
  2. on the second page on the taskbar list is activated and visible in the taskbar and when you tap the taskbar the first pages on the taskbar list activated and comes visible on the screen.

• automation tests were ok
• all apps launched manually ok
• All manual regression tests ok

Issues:
same issues as with Orin AGX. including the disappeared tasbar.
