This is some inter-operation between Cairo (see Cairo) and Gdk
things.
.PP
A \f(CW\*(C`Gtk2::Gdk::Cairo::Context\*(C'\fR lets Cairo draw on a Gdk drawable
(window or pixmap).  It's a Perl-level subclass of \f(CW\*(C`Cairo::Context\*(C'\fR
and the various functions below can be used as methods on it.
.PP
The methods can also be used on other \f(CW\*(C`Cairo::Context\*(C'\fR as plain
functions.  For example \f(CW\*(C`set_source_pixbuf\*(C'\fR can setup to draw from a
\&\f(CW\*(C`Gtk2::Gdk::Pixbuf\*(C'\fR to any Cairo context,
