Implement separate tension and compression components

Fix T50075: Assert during debug render of hair_geom_transmission.blend

fix for physics visualization in FM, strings for constraint identifiers were not displayed properly under windows

Merge branch 'master' into blender2.8

Alembic: quiet compilation warnings on Windows.

Most of them are harmless implicit conversions (e.g. Alembic deals with
doubles for storing time information when Blender uses both ints and
floats/doubles) or class/struct mismatch on forward declarations.

Fix T46795 : Reset GWLP_USERDATA to NULL at window destruction so any future events will not try to reference this deleted class.

Separate shear damping from structural damping

Make structural springs act in both extension and compression

Fix spring force scaling based on length

Fixed bug where projection handle for vertex paint wasn't being allocated, causing texture paint to crash.

Merge branch 'master' into soc-2016-pbvh-painting

Cleanup id->newid usage, initial work.

This aims at always ensuring that ID.newid (and relevant LIB_TAG_NEW)
stay in clean (i.e. cleared) state by default.

To achieve this, instead of clearing after all id copy call (would be
horribly noisy, and bad for performances), we try to completely remove
the setting of id->newid by default when copying a new ID.

This implies that areas actually needing that info (mainly, object editing
area (make single user...) and make local area) have to ensure they set
it themselves as needed.

This is far from simple change, many complex code paths to consider, so
will need some serious testing. :/

Fix crash when accessing id->newid in some cases.

ID->newid was not cleared on reading file, since until now it could be
saved with whatever random value...

Merge branch 'master' into id_newid_optional

Add description for the functions

OCIO: Cleanup style

Was a ground work for some more improvements here, but got dragged
to some other studio maintenance job here.

The plan would be to enable exposure/gamma control for fallback mode
which will definitely be really handy for development and might be
handy for cases when OCIO config can not be read.

More versioning, and more DNA

Alembic: slight cleanup, reorder mesh code a bit.

Fix T49813: crash after changing Alembic cache topology.

Crash is due by mismatching loops and faces counts between the Alembic
data and the Blender derivedmesh which does not appear so
straightforward to fix (the crash happens deep in the derivedmesh code).

So for now, try to detect if the topology has changed and if so, both
only read vertices (vertex colors and UVs won't be read, as tied to face
loops) and add a warning message in the modifier's UI to let the user
know.
