X window system's WINdow CLONE application.
Program aimed to be light-weight and utilise few system resources.
This program can be used to translate another window's content in its own window with some features like background color/image, window centering, start/stop hotkeys,FPS control.
In order to translate window content and grab key combination event, program communicates with xorg server directly using Xlib and its composite and xinput2 extensions. Minimal Xlib's composite extension supported version is 0.2, for xinput2 minimal supported version is 2.2
Window selection mechanism depends on mode, in daemon mode user has to use key combinations to start/stop translation/program, in normal mode after program starts user have some time to change focus to window which content have to be translated. Program registers key press event for root window on all keyboard devices, so your window manager or other program must not grab this keys or entire keyboard.
