"""
All the constants are expressed in pixels. They are defined for the XO screen
and are usually adapted to different resolution by applying a zoom factor. The
factor for traditional 96 dpi screen is currently 0.72 which is the inverse
of the one we are using to adapt web pages to the XO screen. It should be
considered a reference value rather then a scale constant which has to be
automatically applied and always respected.
