GTK : Fine tuning gnome theme ?

[Vincent Trouilliez]

I would like to "fine tune" Gnome's "Simple" theme.

I found it in  /usr/share/themes/Simple

I played with the Metacity XML file that controls window borders, but I
would like to modifiy the Gtk theme. 

The gtkrc file is some explanatory to some extent, so experimented a
bit, but I am still kinda shooting in the dark

Is there documentation out there, on how to modify a gtkrc file ? That
is, the structure if the file, what are all the things you can modify,
all the options and valid parameters, what they do exactly, so that I
can make exactly what I want ?

Then, is there some user friendly GUI program that makes it easy to
modify a gtkrc file ?

And where can I get the normal "show desktop" icon ? The one in Ubuntu
is not the same as the one you can see in Gnome official preview :

I like the "Simple" theme, and also "Glider". But both have little
things that annoy me, so I keep switching back and forth between the two
every few weeks. So I would like to spend some time to make them
perfect, so that I can be really happy with either of them, and stop
changing themes all the time.

On a related note, does anyone know how to turn the "prelight" feature
OFF, and also the "tootips", and also the ridiculous window animation
you get when you minimize a window ?
All these things give me headaches... :-/

Vince
