Native Wayland Support

[bwRavencl]

💡 Motivation

While ControllerBuddy functions correctly via XWayland, implementing native Wayland support would be desireable.
This aligns with the ongoing work in Project Wakefield for native Wayland support in the OpenJDK.

🏗️ Current State

Preliminary support is currently being tracked in the wayland branch.
This implementation utilizes JBR25 because it ships with an experimental Wayland AWT Toolkit.

🚧 Remaining Issues

• Window Positioning: Windows are not positioned correctly on launch - concerns Overlay and On-Screen-Keyboard.
• Icon: Application icon is not displaying in the dock/taskbar.
• Cursor: Custom cursors are not displayed - concerns Visualization Tab.
• Always on Top: Overlay and On-Screen-Keyboard windows lack "Always on Top" functionality.
  Note: This requires implementation of the xdg-pip protocol.

🛠️ Workaround: "Always on Top" (KDE Plasma)

Until the xdg-pip protocol is supported, KDE users can force the overlay behavior by adding a custom KWin rule to ~/.config/kwinrulesrc:

[General]
count=1
rules=bc527ade-2339-4555-b784-c8c31e7099cd

[bc527ade-2339-4555-b784-c8c31e7099cd]
Description=ControllerBuddy Window Rules
layer=overlay
layerrule=2
title=Overlay|OnScreenKeyboard
titlematch=3
wmclass=de.bwravencl.controllerbuddy/de.bwravencl.controllerbuddy.gui.Main
wmclassmatch=1

A programmatic creation of KWin rules could be implemented similar to this.
