Parameters
----------
win : `psychopy.visual.Window` instance
PsychoPy Window (usually not fully created yet).
backendConf : `dict` or `None`
Backend configuration options. Options are specified as a dictionary
where keys are option names and values are settings. For this
backend the following options are available:
* `share` (`psychopy.visual.Window instance`) PsychoPy Window to
share a context with.
* `refreshHz` (`int`) Refresh rate in Hertz.
* `bpc` (`array_like`) Bits per color (R, G, B).
* `swapInterval` (`int`) Swap interval for the current OpenGL
context.
* `depthBits` (`int`) Framebuffer (back buffer) depth bits.
* `stencilBits` (`int`) Framebuffer (back buffer) stencil bits.
* `winTitle` (`str`) Optional window title string.
Examples
--------
Create a window using the GLFW backend and specify custom options::
