Application for Forking UKUI-KWin from KWin

[MouseZhang]

Hi David:

Tablet Mode:

In the UKUI desktop environment, besides manually switching,
the switching between PC and tablet mode can also be triggered
by listening to keyboard plug-and-unplug events. Some components
also respond to these plug-and-unplug signals to transition between PC
and tablet mode. Furthermore, there is a window called "blur background,”
which appears underneath the active window (more precisely,
under all windows of the active window's process), regardless of
whether the window can be maximized or has child windows. Similar to the image below:

Virtual Keyboard:

Now, the virtual keyboard works well on X11, there are terrible bugs on wayland,
but we will support wayland in the future.

On x11, it will be covered by popup window:

Dependencies:

I removed all debian package which name contains “plasma”, then “sudo apt install kwin-x11 kwin-wayland”.
Plasma-workspace and plasma-workspace-wayland and …will be installed. This is one of the reasons
why we want to fork the ukui-kwin.

Wayland is the future, but currently, it's not stable enough, and we will do our best to address its shortcomings.
Our users, on the other hand, prefer to use a more stable desktop environment and some applications
that are only supported on X11. Hence, we need to support both X11 and Wayland simultaneously.

Best regards,

Mouse Zhang
