Changes proposed in this pull request:
ImageGrab.grab()support for X11 (Linux) using the XCB library (only screenshots for now, clipboard can be added in the future)There is also support for taking X11 screenshots on Windows and macOS (where X11 can be installed as a separate window manager). This proposed implementation uses the old methods if
xdisplay=Noneis passed, but ifxdisplay=""is passed (or on Linux), it will grab the default X11 screen (likely from the DISPLAY envvar). A different value can be passed in thexdisplayparameter to override the default X11 screen address.Unlike mss which uses Xlib, this uses XCB. This provides more resilient error handling at the cost of potentially slightly lower OS compatibility (Xlib is older).
