New rounded end caps

Now the stroke ends are rounded to get more artistic look.

Fix triangles indexbuf of Curve Displists was being discarded incorrectly

They were discarded when shaded surfaces were requested thus bringing glitches to the outline of the selected Displists Objects

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

allow rigidbody being a forcefield effector too

this was disabled intentionally for some unknown reason

CMake: bump minimum version to 3.5

Merge branch 'blender2.8' into greasepencil-object

Fix multiframe error when lock layer

There was a segment fault if the some layer was locked and enable multiframe edit / sculpt or weight paint.

The shading group must be created because is used in multiedit lines.

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.

fix, threshold and cluster threshold application was swapped

WIP: Experimental Offscreen buffer for fill

Simple implementation of stroke drawing to texture

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.
