stock keybindings, images

[Evan Martin <martine cs washington edu>]

keybindings:
I notice the Emacs keytheme uses "<shift><ctrl>" modifiers for some of 
its commands.  Doesn't GTK intercept shift+ctrl+hexdigit for entering 
Unicode characters?  This makes many of the keybindings (in fact, all 
shift-control keybindings specified in gtk-emacs-text-entry) not work-- 
hitting shift-control-b tries to insert Unicode character 0xB.

images:
Is there a reason the stock yes/no images aren't antialiased against 
transparency while the other images are?
