Get location in scene for pixel?

Question

Given a pixel on the rendered image, is there any easy way to get the 3D location that the pixel corresponds to in the scene using python? i would really like to know before I go through trying to do the math to get it myself.

In case it makes a difference, I'm using an orthographic camera.

It is possible in the game engine, using the 'kx_camera.getScreenVect()' call. Not sure about the viewport. — Mike Pan, Feb 17 '14 at 20:27
It's possible in the viewport too, but rendered image? Not sure... What is the application? — CodeManX, Feb 17 '14 at 23:50

There are utility functions to convert 2d region coordinates to 3d:

bpy_extras.view3d_utils

There's also a method to cast a ray in the scene:

Scene.ray_cast

... but it might not work with orthographic view.
