Add an option to turn on the use of the X window's alpha channel in multiwindow mode, i.e. this uses the X window's alpha channel for compositing into the native desktop. This works on W7/Vista (using DwmEnableBlurBehindWindow()), and Windows 10 (using the undocumented SetWindowCompositionAttribute()), but not on Windows 8/8.1 -compositewm must be enabled for this to be useful, as we only have a pixmap with an alpha channel for the X window in that case. The framebuffer/root window doesn't have one (unless perhaps you are using the rootless extension, maybe...). v2: Update meson.build Future work: A window property to control use of alpha? Option to turn off blur on W7/Vista Implement _NET_WM_WINDOW_OPACITY
