Allows playing video with alpha information on X11, as long as the video contains alpha and the window manager does compositing. See vo.rst. Whether a window can be transparent is decided by the choice of the X Visual used for window creation. Unfortunately, there's no direct way to request such a Visual through the GLX or the X API, and use of the XRender extension is required to find out whether a Visual implies a framebuffer with alpha used by XRender (see for example [1]). Instead of depending on the XRender wrapper library (which would require annoying configure checks, even though XRender is virtually always supported), use a simple heuristics to find out whether a Visual has alpha. Since getting it wrong just means an optional feature will not work as expected, we consider this ok.
