Fix T75881: Animation, limitation of Bézier Handles

Relax limits of FCurve Bézier handles during evaluation. FCurve handles
can be scaled down to avoid the curve looping backward in time. This
scaling was done correctly but over-carefully, posing unnecessary
limitations on the possible slope of FCurves. This commit changes the
scaling approach such that the FCurve can become near-vertical.

Bump Blender's subversion from 291.0.1 to 291.0.2 to ensure that older
animation files are correctly updated.
