Window
The type of the window backdrop/background.
Fallback Strategy
In case of unsupported effect the library tries to fall back to the nearest supported effect as follows:
Tabbed ->Mica ->Acrylic ->Transparent
Aero is dropped from the fallback as it is much more transparent than Tabbed or Mica and not customizable as Acrylic. If Tabbed or Mica falls back to Acrylic or Transparent, high alpha is used with white or black color according to isDarkTheme to emulate these effects.
Types
This applies Aero backdrop which is Windows Vista and Windows 7 version of blur.
This effect provides a simple solid backdrop colored as white or black according to isDarkTheme. This allows the backdrop to blend with the title bar as well. Though its name may imply that the window will be left unchanged, this is not the case as once the transparency is hacked into the window, it can't be reverted.
This applies Mica backdrop themed according to isDarkTheme value.
This applies color as a solid background which means that any alpha component is ignored and the color is rendered as opaque.
This applies Tabbed backdrop themed according to isDarkTheme value. This is a backdrop that is similar to Mica but targeted at tabbed windows.
