Description

This would use the same method as ofxGrabCam (pull a pixel from the depth buffer and unproject)
Anybody have any qualms about including this in ofCamera directly?

also i suggest we add:
glEnable(GL_DEPTH_FUNC); to ofCamera::begin(...)

Research direction

Start by comparing the proposed ofCamera::getXYZat(const ofVec2f & screenCoordinate) behavior with the method used by ofxGrabCam, focusing on depth-buffer pixel lookup and unprojection. Review ofCamera::begin(...) for the suggested depth-function change; done means the API behavior and depth handling are specified and validated against the existing camera workflow.
