Make rounded corners in Blur theme for Windows 10

Windows 10 - no rounded corners

Windows 11 - rounded corners

One way to get rounded corners is to use MagickMeter plugin instead of FrostedGlass

Here are disadvantages of this way:

• Skin ignores any window under the skin and shows only blurred wallpaper
  
• It gets laggy while dragging the skin around the screen as it redraws its background every second only

Other way is to hope that feature would be implemented in FrostedGlass plugin
I left them an issue: TheAzack9/FrostedGlass#5

I found another workaround. It will be implemented in v2.0
