Use "Location" consistently

Remove unecessary checks for zero

Add plane primitive node

Merge branch 'master' into temp-gpencil-bezier-stroke-type

GPencil: seperate for bezier strokes operator

This also adds a "Keep Ends" option that will keep the ends on both
parts, which is especially useful with curves.

GPencil: add transform modes for bezier strokes

Add the opacity/shrink/fatten transform modes for bezier strokes.

GPencil: subdivide bezier strokes operator

GPecnil: flip bezier strokes operator

GPencil: join bezier strokes operator

This also implements the flip BKE for curves.

Sculpt: Apply latest clang-format changes to the branch

Merge branch 'master' into sculpt-dev

Cleanup: Clang format

Sculpt: Fair all by tangency mode for face set edit

Fixed up the TODOs re materials left when making it compile again.

Also, fixed a place where a newline belonged in material output.

GPencil: Toggle end caps curves operator

GPencil: set cyclic curves operator

GPencil: change material curves operator

GPencil: Arrange curves operator

GPencil: comments

GPencil: reproject curves

This is using the "easy" way of reprojecting the points first,
then refitting the curve. A better solution would be to project the
curve points and then recalculate the stroke. This would also be less
computational expensive since fitting the curve is slower.
