The Stroke panel's Profile list now holds saved profiles next to the built-ins,
kept with the preferences (Prefs.width_profiles). Add to Profiles… names the
selected stroke's variable width, Delete Profile removes the selected stroke's
saved one (built-ins can't be deleted), Reset Profiles removes them all.
Three more generated built-ins (Pinch, Teardrop, Wave). The dropdown (Stroke
panel and Control bar) lists saved profiles and draws a custom profile's own
silhouette. Commands: stroke.widthProfile.add/delete/reset/list; stroke.set
{profile} takes a built-in id or a saved name.
