sylph-decoder 3d8b1c2d4b tools: the sweep leaf's declared ramp, and the slope measured off the GPU ...

sweep_leaf_ramp dumps the nested ptloop01/ptloop02 leaf keyframes -- position,
alpha, rotation, scale and time -- which is where the ramp the port asked for
actually lives.

sweep_positions now also pools alpha against position per strip and prints the
slope, with the quantisation stated: NDC prints to two decimals, so one frame's
dx is 6.4 px and alpha is one level, and at three or four frames the two
declared slopes (+0.0814 and -0.0651) are inside that noise. It is a direction
and magnitude check, not a discrimination.
