glfwSetWindowOpacity

Sets the opacity of the whole window.

This function sets the opacity of the window, including any decorations.

The opacity (or alpha) value is a positive finite number between zero and one, where zero is fully transparent and one is fully opaque.

The initial opacity value for newly created windows is one.

A window created with framebuffer transparency may not use whole window transparency. The results of doing this are undefined.
