[webkit-dev] RFC: Creating header include policy for Gtk+

Hey fellow reviewers,
I would like to establish a new policy for the Gtk+ port and use mail to get
comments and agreement on it.
Our header files (*.h) have a lot of include statements. This is a problem
(specially without using precompiled headers, we don't on Gtk+) because we
instruct the preprocessor to search for these header files and our compiler
needs to parse through these. One specific problem we face in the Gtk+ side of
things are innocently looking includes like cairo.h. cairo-ft.h, gtk/gtk.h.
They will resolve to a load of other includes... In the case of gtk it is all
glib headers, all glib-object headers (the two/three), each and every
GtkWidget, or in the case of cairo-ft we get the whole set of freetype
headers. This can easily increase the list of to be included files... by one
The proposed solution and policy:
Ban cairo.h, gtk.h, gdk.h, glib.h, glib-object.h, soup.h from header files and
replace the structures and inlined calls with forward declaration.
I have created a bug/patch to look at the impact of this new policy and I
probably still need to show that this approach is any faster.
