From 289949d0c43e4753ecc77ee05ee2092c893f7941 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 4 Jul 2014 16:59:50 +0200 Subject: [PATCH] accel_profile_smooth_simple: Make 0.0-1.0 accel range depend on threshold Instead of always going from an accel of 0.0 to 1.0 between a velocity of 0.0 and 1.0, make the lead-in length of the curve depend on the threshold setting, using half of the threshold for the lead-in.
