 # Internal representation of a keyframe, that carries info on the frame location in the clip, x y and residual.
 #
 # Franme numbers are zero-based (frame 0 is first frame of the clip).
 # X-coordinate (abs_x) is absolute pixels from lower left corner of the comp to the right
 # Y-coordinate (abs_y) is absolute pixels from lower left corner of the comp up
 # Residual is how far in pixels the tracker strolls away, and is the inverse of
 # correlation (with total correlation of one the residual excursion becomes zero).
