…luences the rendercapture image in a way that it is flipped in y too (relevant for the bookmarks and boblight). glReadPixels always returns a y flipped image - so we flip it via matrices before rendering the capture image - for corevideobuf we now skip the flip for fixing the upside down bookmarks (commented with fixme - because we still don't understand why this is affecting rendercapture at all)
