Sort functions and standardize formatting.

The new version no longer checks the return code of `SDL_GetWindowOpacity`, for consistency with the other getters. In theory this should be fine, because the only documented error condition is if the window is invalid, at which point none of the getters matter. If the platform doesn't support transparency, "opacity will be reported as 1.0f without error."
