CursorCentered Fix

Experimentally support setting cursor position on wayland using ydotool.

Important Notes

This feature depends on ydotool which needs to be installed and configured manually, here are the major steps:
1.Install ydotool if it doesn't exist.
2.Make your user be able to run sudo command without password(edit /etc/sudoers, add a line <yourusername> ALL=(ALL) NOPASSWD:ALL)

Since this feature is implemeted by executing external process, you may experience lags while opening guis frequently.
