Rodrigo Tobar 2331fe5e68 LibPDF: Add first interpolation methods
Interpolation is needed in more than one place, and I couldn't find a
central place where I could borrow a readily available interpolation
routine, so I've implemented the first simple interpolation object. More
will follow for more complex scenarios.
