This includes: * getting cursor image through xcb_xfixes * using xcb_image_get for reading screen content in xrender case * using xcb_put_image to upload the generated screenshot into shared xpix Overall this means that QPixmap as an X Pixmap wrapper is no longer used. The conversion from xcb_image_t to QImage still needs some code for not matching byte order. I'm a little bit unsure about adding the code as I would not be able to test it. REVIEW: 109076
