Its the same as with xcb or Xlib.
Both aren't used a lot directly by application programmers, instead
programmers use QT4/Gtk or Java2D as "sanitizing libraries"
Xlib's task is to allow access to the X11 protocol from C, exatly what
libXrender does for the RENDER extension.

libXRender only contains X11 protocol generation and a few definitions.
If Cairo/QT4/... would have to generate the protocol themself, it
would probably lead to a lot of duplicate code and bloat.

Well, thats exactly what the protocol specification is about, it
contains everything you need to know to implement a library.

However, the protocol specification is not a programmer manual howto
use RENDER or libXRender, and at least what I've heard, this is what
most people are asking for (including myself about a year ago ;) ).
