sdlSetWindowOpacity function
Set the opacity for a window.
The parameter opacity
will be clamped internally between 0.0f
(transparent) and 1.0f (opaque).
This function also returns -1 if setting the opacity isn't supported.
\param window the window which will be made transparent or opaque \param opacity the opacity value (0.0f - transparent, 1.0f - opaque) \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
\since This function is available since SDL 2.0.5.
