The X11 Nonrectangular Window Shape Extension is the answer you're looking for.

You may be getting confused by the description of this protocol as an "extension". X11 implements many features as extensions to the base protocol. It doesn't mean that these features are nonstandard or that they should be avoided; it just means they weren't part of X11 when it was released in 1987.
