ImageZMerge

The ImageZMerge node applies a simple A over B composite. A and B are determined by examining the corresponding depth image and making A the image that has the lower (closer) depth value. A depth of 0 is assumed to be infinitely far away. An accumulated depth for the result is also available as the second output. Inputs are ordered as follows: Image1, Depth1, Image2, Depth2.
