Drop shadow madness

Okay,
First off
I don't expect to see this committed.
Ever.
It's a hack.
There's even a hack inside the hack
Thats how hacky this hacky hack is.

But I've been using it for a week now
And I love it.
It seems to add a modicum of class
And style to my otherwise dreery drab desktop.

So I am sharing it with the rest of the world.
But, like I say
It's a hack.
There's occasions where it won't look right.
And those occasions will never look right
With this hack.
I know about them
I don't care about them.
If it breaks - 
Congratulations, you get to keep all the bits.

And so, without further ado...
I give you
the gtkmenu drop shadow hack

Taadaa!
(and yes, I nicked the arrays of values off of kde-look.org
 which means that if you apply that patch to your KDE, then
 the two drop shadows will look the same)

Enjoy
