* \brief A variable controlling whether the EGL window is allowed to be
* composited as transparent, rather than opaque.
*
* Most window systems will always render windows opaque, even if the surface
* format has an alpha channel. This is not always true, however, so by default
* SDL will try to enforce opaque composition. To override this behavior, you
* can set this hint to "1".
