BitmapDisplacement modifier. Displaces verttices based on RGB values of pixels.
BitmapDisplacement is inspired by both the AS3 built-in DisplacementMapFilter. It allows
to use color values for each channels of a bitmap to modify the position of vertices in a mesh.
The displacement taks place along the cardinal axes, and each axis is mapped to a
channel in the bitmap: X for Red, Y for Green and Z for Blue.
