GPUFramebuffer: Add support to attach individual texture layer.

Cleaun: Add clamp to keep zdepth in valid range

Cleanup and move constant to defines

Fix keep thicknees by object

This option must be by object, not by scene.

Cleanup some code too and rename to use better naming for variables.

Manipulator: de-duplicate flags and scale option

Merge branch '28' into custom-manipulators

Cleanup: move copy-paste code into function

Merge branch 'master' into soc-2017-normal-tools

Added normals to follow mouse location.

Now M key can be used after ALT - L to have clnors point to mouse location.

Merge branch 'master' into blender2.8

Cleanup: doxygen comments

Also remove duplicate & mismatching comments from grease-pencil header.
Keep comments close to implementation to avoid getting out of sync.

Fix T51774: Children particles hair interpolation not correct with textures or dp.

Children where always getting at least one segment of fixed length...

Now fully hidden ones (zero length) get no segment at all.

Note that even very short ones keep getting one 'unit' length segment - would
rather avoid changing that at this point, given how complex children
particles 'length' can get with all kind of modifiers... Think we can
live with that for now anyway.

Add mid range for zfight

Modified do_topo_brush

WIP: adjust the shift factor with distance

added deform weakening factor

the threshold is multiplied with 1.0-fac per deform iteration, so it can automatically break at some point.

Cleanup: Remove unused code

WIP: zfighting al most fixed.

Need a way to fix the problem of zdepth and precision

added additional distances and angles settings in order to control plastic deform better

Fix T51840: UI redraw in node editor header missing on pointcache bake

Missing a notifier handler in the node editor
