[gtkdatabox] updated cairo-alpha branch

["Amish S. Dave" <amish amishdave net>]

I've pushed my gtk3 patches to the cairo-alpha branch.

I also brought that branch up to speed with some of Matt's and Lars' 
patches to the master branch.

the box shadow patches are in, but not really supported (not translated 
into cairo commands yet).



There is a bug in the setting the location of vertically oriented text 
on a vertically oriented ruler.  Anyone up for tracking this down?

Sincerely,
