P: End points in curves scale badly with "amount" preset slider

[Ailinon]

First and last points in a curve setting don't scale properly when Preset Amount slider is used:

1. Before preset:

2. Applying preset:

3. Amount slider to 0%:

Windows, LR Classic 13.4.

I've been able to reproduce this issue. Note: this is being moved from LrC to Camera Raw as it is an underlying problem with the CR engine - not the LrC application.
