Another fix for particle instance child lookups, was not subtracting
parent amount.

Fix for particle instance initial frames.

These were not orthonormal and tended to flip with changing hair
direction, now use the particle hair matrix which is stable wrt. the
mesh surface.

Randomness factor for hair bending stiffness.

This helps to create some variation in a hair system, which can
otherwise become very uniform and boring. It's yet another confusing
setting in a system that should have been nodified, but only option for
now (broken windows ...)

Fix for applying the bending randomness factor.

A stupid hack is needed here, changing the way the factor is applied to
angular bending springs. In cloth sim the bending factor of individual
springs is applied as a mix value between the bending stiffness and a
max value, but this max value isn't even used in hair sim so that
approach becomes useless.

Fix T42639, editcurve flags not getting restored on undo.

Error here could be reproduced by tweaking curve properties such as
2d-3d or fill type and undoing.

Initialize the snaping aspect just once.

Bring back the old manipulator code, it works better with the transform
system for now. Backup the old code in a new file

Borrow transform system interaction: When arrow direction has direction
close to view direction, use up/down movement of mouse to calculate
offset.

More refinement to the widget system. Now camera widget should be
indistinguishable than the displayed widget (might probably be worth
deleting the original)

Arrow Widget:

Create a cross style widget, with wireframe cross.

Allows setting a custom scale for the arrow widget also, an up
orientation.

Add flag so widgets only draw on mouse over.

Camera widget now uses this, also now they only draw if limits is on.
