manpage: document background transparency
--alpha=yes doesn't affect only transparent videos and images, but also
the background. I spent time researching how to implement transparent
backgrounds and had no idea that they already worked at least on
Wayland.
Background transparency will work on X11 when
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/2376 is
merged. It doesn't work on Windows. No idea about macOS. Either way,
this paragraph already says that it only works on certain environments
twice.
