gtk/gdk/broadway/broadway.js
Alexander Larsson 7d37534ee2 [broadway] Implement keyboard event better 
We're using the noVNC keyboard even handling model (and some of the
code with permissions). This means we combine data from keydown and
keypress to figure out the translated keysyms according to the keyboard
layout at the users machine.
