Two smoothness refinements on the local wheel path: the drain factor
drops from 35% to 22% per frame, so the first frame of a notch takes a
smaller step and the glide lasts longer; and local scrolling accumulates
FRACTIONAL lines (_wheelScrollLinesFloat) instead of rounding every
event, so a slow macOS trackpad drag no longer snaps a whole line per
tiny delta (the old ±1 fallback made slow drags scroll faster than the
finger). Sub-line residuals stay pending until further input crosses a
whole line. Forwarded SGR ticks keep the rounded integer path. Probe:
a 20-line notch now glides through 14 positions to an exact landing;
the 9-check scroll matrix still passes.
