This class is intended to be passed up a vertex shader tree. It's initialized with basic vertex info like the point location, a UV coordinate and a normal. A shader can then modify the parameters producing effects like point displacement, UV projection, and normal remapping.
Use the UV and the derivatives of UV to sample the incoming image. UV of 0,0 is mapped to the lower-left corner of the image's format, and 1,1 is mapped to the upper-right corner.
