GPencil: Recalc triangulation for active frame and delay others

cleanup

fix generating operation hash

this needs some more work

assert data types when inserting links

new Vector Length node

fix memory leak

new normalize vector node

fix stack use out of scope error

vectorize Map Range node

new ceil and floor float nodes

Merge branch 'master' into functions

GPencil: Use bounding box collision instead of radius

UI: fix blurring of bitmap icons for the navigation gizmo

Merge branch 'blender-v2.82-release'

Fix error showing viewport units

Out of bounds buffer unit-system index with zoomed out viewport.

Cleanup: clang-format

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.
