lily/line-spanner.cc:371: // actual stencil bounds may be different
The actual stencil bounds are (inf , -inf) if someone sets style=none
When I try this on input/regression/dynamics-alignment-no-line.ly the
while loop in add_grobs_of_one_priority() takes forever.

lily/line-spanner.cc:377: Real new_left_y = minmax (-d, extremity,
line_left[Y_AXIS] + d * skyline_spanner_padding);
The smaller of the extent of the cresc.--- and the line padded by
skyline_spanner_padding.  Is that what you want?
