Merge branch 'master' into functions

GPencil: Use bounding box collision instead of radius

GPencil: Add collision checking for Sculpt

Instead to check all points, first a general stroke checking is done in order to avoid reading thousands of points.

Refactor readfile's liblink code.

Liblink specific ID type function was so far running a loop over all IDs
of relevant type, unlike almost any other 'ID-callback-like' functions
in Blender, which usually let the looping controll to calling code.

The latter approach is more convinient when one want to add generic
(i.e. type-agnostic) code, since it typically only has to change code in
one place (caller function) instead of tens of places (all the callback
functions).

This commit also changes/sanitizes a few things that had nothing to do
in main liblink code, like mesh conversion from tessfaces to polys
(which can be done in after-linking versionning code), or scenes' cycles
detection/check regarding background 'set' scenes.

Reduce the calculation of filling geometry and matrix repetitive.

Objects: modifier stack integration for hair, point clouds and volumes

This is more a prototype for testing, it's not clear yet if we want to use
the existing modifier stack or immediately go to nodes.

Currently working are a few deform modifiers for hair and points clouds.
The infrastructure for constructive modifiers is there as well, just none
are implemented.

GPencil: Cleanup unused function

Hair: add initial Cycles rendering support

GPencil: In multiframe show only lines for non active frame

When use multiframe, it's important to see in full color only the active frame, and the other frames just with a line if the option is enabled.
