Dear Maintainer,

i just wanted to look up the description of cogl functions with devhelp that
begin with 'cogl_path_*'. I expect to find the descriptions just like on

https://developer.gnome.org/cogl/1.14/cogl-Path-Primitives.html

Unfortunately the local 'Path Primitives' page of the cogl reference manual is
empty, despite some headings (Path Primitives, Description, Functions, Types
and Values). Not even one function is described. All other pages of the cogl
manual contain the full description.

I compared this with the references listed at

https://developer.gnome.org/cogl/

and found that the last reference version that contains the whole information
is 1.14.0. Strangely those information are omitted in both version 1.16.2 and
1.18.2.

It would be great if it will be fixed. Thank you for your effort
