Blender Git Loki

Fix triangles of the Displists were being drawn in the opposite direction

CMake: bump minimum version to 3.5

Manipulator: change cursor for navigation axis

Wasn't easy to see

Manipulator: draw 2d manipulators over view border

Needed so passepartout doesn't cover 2d manipulators.

App Template: use manipulator flag

So templates can enable manipulators.
Also remove invalid enum set.

Manipulator: view3d navigation buttons

Added for Blender101 template.
Disabled by default, enable as a preference.

Exposes rotate, pan, zoom, persp-ortho & camera toggle.

Manipulator: support single press button actions

While not the main purpose of manipulators, it's handy to be able
to use operators without modal callbacks sometimes.

Merge branch 'master' into blender2.8

Depsgraph: Cleanup, remove unused function

Depsgraph: Cleanup, make naming more understandable

Depsgraph: Use array instead of set for node factory

Avoids extra time spent on hashing and such.

Old comment is kind of weird, because types we can totally make a sequent
integer values.

Depsgraph: Add named constant with number of node types

Depsgraph: Don't use negative enum value

Not sure why it sohuld be negative, we shouldn't be using any explicit value
comparison.

Fix failing assert when reading workspace list from workspaces.blend

Merge branch 'master' into blender2.8

Depsgraph Cleanup, spelling

Depsgraph: Simplify logic around special case for node tree update

Depsgraph: Cleanup, extra whitespace

Depsgraph: Cleanup, use names for particle system tag flags

Depsgraph: Remove special exception logic from ID node tagging

This is something what we should be limiting as much as possible, it is
enough already to have special mapping cases in depsgreaph_depsgraph_tag.
