move adjancent keyframes and keep slope orientation

[Kris Rivel <krisrivel(at)gmail.com>]

Is there a way to move key frames using the "Plateau (horizontal for 
local min & max)" and keep their slope orientation intact?  With it on, 
if you move a key frame above its original value, the adjacent keyframes 
that have the same value re-adjust their slope orientation.  I can't 
seem to prevent them from doing that.  Here's a simple script that 
animates a null to show what I mean.  Grab the 3rd keyframe and move it 
up and down in the fcurve editor:

NewScene(null, null);
SetValue("preferences.animation.tangentori", 1, null);
GetPrim("Null", null, null, null);
SaveKey("null.kine.local.posx,null.kine.local.posy,null.kine.local.posz", 
1, null, null);
SetValue("PlayControl.Key", 24, null);
SetValue("PlayControl.Current", 24, null);
Translate(null, 0, 4.49802037804679, 0, siRelative, siLocal, siObj, 
siXYZ, null, null, null, null, null, null, null, null, null, 0, null);
SaveKey("null.kine.local.posx,null.kine.local.posy,null.kine.local.posz", 
24, null, null);
SetValue("PlayControl.Key", 42, null);
SetValue("PlayControl.Current", 42, null);
SaveKey("null.kine.local.posx,null.kine.local.posy,null.kine.local.posz", 
42, null, null);
SetValue("PlayControl.Key", 60, null);
SetValue("PlayControl.Current", 60, null);
Translate(null, 0, 5.90916402606146, 0, siRelative, siLocal, siObj, 
siXYZ, null, null, null, null, null, null, null, null, null, 0, null);
SaveKey("null.kine.local.posx,null.kine.local.posy,null.kine.local.posz", 
60, null, null);
