That is a reason a Wayland compositor does *not* need to do drawing.

It sounded like there is a requirement that a compositor must be able to 
do drawing, which I don't understand.

Admittedly in any real compositor it will probably do it's own drawing, 
for things like popup menus or to draw the panel. But I got the 
impression that this is not a requirement. I can certainly imagine a 
compositor that either avoids all that or launches clients for all these 
things.
