Now I forgot that I did prior change here, so values were incorrect :(

Add origin modes from scene tool settings.

Merge changes from transform_gizmos - these patches can't be developped separately anymore

Add support for individual origins pivot point

Use pivot point from sequencer tool settings, Limit pivot points to implemented and useful modes.

Cleanup: remove unnecessary clamp, is already done when initializing closure

Fix deadlock due to lock order inversion in rendering after GPU display changes

Main thread:
* Acquires DST.gl_context_mutex lock for drawing image editor
* Acquires mutex_ in GPUDisplay::draw()

Render thread:
* Acquires mutex_ in GPUDisplay::update_begin()
* Acquires DST.gl_context_mutex for updating texture

Ideally DST.gl_context_mutex would not be needed at all, for best performance.
But this requires deep changes to the draw manager since it relies on global
variables in many places.

Instead rely on DST.gl_context_mutex for mutual exclusion between update and
draw operations in the subclass, and only use mutex_ for thread safe access to
the parameters.

Functions: support optional outputs in multi-function

Sometimes not all outputs of a multi-function are required by the
caller. In those cases it would be a waste of compute resources
to calculate the unused values anyway. Now, the caller of a
multi-function can specify when a specific output is not used.
The called function can check if an output is unused and may
ignore it. Multi-functions can still computed unused outputs as
before if they don't want to check if a specific output is unused.

The multi-function procedure system has been updated to support
ignored outputs in call instructions. An ignored output just has no
variable assigned to it.

The field system has been updated to generate a multi-function
procedure where unused outputs are ignored.

Geometry Nodes: fix memory leak for multi input sockets

Fix error while freeing non primitive collisions shape mesh in rigidbody

The function name was changed in master and caused an error during merge
Now it uses a different function to clear the geometry

Fixed out of scope error

Merge branch 'master' into soc-2021-simulation-display

Made changes according to revision suggestions

make format

Constraints: visualisation works with kinematic objects

Used the transforms obtained from bullet instead of creating them using
rigidbody/ object data, which only worked for active rigidbodies

Switched radius mode to take a field input

Fix using reference to a temporary variable in Cycles X

Made changes according to revision

Merge branch 'master' into soc-2021-curve-fillet

Fix T90862: Texts in Outliner can have wrong icon

In contrast to the Filebrowser, the Outliner (Blender File view) did not
distinguish icons for text-based formats (if they have a filepath this
can be done though).
