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.

The blend map reports a quad's SIZE, which identifies an element and says nothing
about whether it is visible -- a parked quad is still a draw call. This prints
the NDC x/y range and per-vertex colour of every additive draw, per frame, so
movement between frames and overlap with the [-1,1] box are readable directly.
Written because sylpheed-port flagged exactly that conflation in my blend page:
the blend and the visibility arrived in the same artefact.
