Request for New Wayland Protocol to Improve Window Taskbar Progress Features

Hello everyone! The Window Taskbar Progress PR looks very well.

This pull request for GLFW introduces the following features:

  • The glfwSetWindowProgressIndicator() function, which allows displaying the progress of an action in the dock or taskbar.
  • The GLFW_PROGRESS_INDICATOR_DISABLED value, which stops displaying the progress.
  • The GLFW_PROGRESS_INDICATOR_INDETERMINATE value, which displays the progress in an indeterminate state. On Windows, this cycles the progress from 0% to 100% repeatedly.
  • The GLFW_PROGRESS_INDICATOR_NORMAL value, which displays the user-defined progress status (0%-100%) on the taskbar.
  • The GLFW_PROGRESS_INDICATOR_ERROR value, which displays an error progress.
  • The GLFW_PROGRESS_INDICATOR_PAUSED value, which displays a paused progress.

Currently, on Linux, the Unity LauncherAPI is used via DBus. However, this API requires a valid application .desktop file with the same name as the executable. It seems that only KDE and the Unity desktop environment utilize this API.

If it would be possible to add a new protocol that could better implement these features?
