The radius component is only one float. This resulted in only a third of
intended points to draw and could lead to glitches.
Pointcloud drawing will still change a lot in the future, this is just
to be able to work on some simple tools.

Since rBcf258b02f449, only wires and edges that are mapped to the
original mesh were drawn if the mesh was modified by modifiers.
Above commit was only meant for showing orig wires for paint mask
overlays [where final wireframe is not desired], so now only use
MR_EXTRACT_MAPPED when we are in a paint mode.

The files are now split up into the following sections:
- `BKE_anim_path.h` and `anim_path.c` for path/curve functions.
- `BKE_anim_visualization.h` and `anim_visualizationanim_path.c` for
animation visualization (mostly motion paths).
- `BKE_duplilist.h` for DupliList function declarations. These were
already implemented in `object_dupli.c`, so they were rather out of
place being declared in `BKE_anim.h` in the first place.
No functional changes.
In Blender 2.81 we update and draw all nodes inside the view planes.
When navigating with a pen tablet after an operation that tags the whole
mesh to update (like undo or inverting the mask), this introduces some
lag as nodes are updating when they enter the view. The viewport is not
fully responsive again until all nodes have entered the view after the
operation.
This commit delays nodes updates until the view navigation stops, so the
viewport navigation is always fully responsive. This introduces some
artifacts while navigating, so it can be disabled if you don't want to
see them.
I'm storing the update planes in the PBVH. This way I can add support
for some tools to update in real-time only the nodes inside this plane
while running the operator, like the mesh filter.

Draw batch extraction wrongly assumed that when mapped extraction
happened that all original data could be found. This is not the case as
mapped extraction is also enabled when part of the data is present.
This fix does additional nullptr checks.
EEVEE and Workbench both had the same issue that they continue with the
last sample when leaving navigating. This is ok for regular meshes as
they are all the same. For multiresolution it ain't as a low res version
of the mesh is used during navigation.
This patch also resets the AA samples when the user leaves navigation.
When using generative modifiers too many center dots were rendered in
the normal overlay. This patch only renders the normals of original
center dots.
Known issue: decoding the `norAndFlag` has issues on Intel GPU.
The loop normals were always drawn. We used to only draw the normals if
it was mapped to an original loop of the mesh. Due to recent changes we
can not find the correct loop and decide if we need to draw them.
Note still need to check the face dots normals. This is more complicated
as facedot normals needs to be encoded in a different way
The paint mask overlay showed the wires and edges of the final mesh.
This change will only draw wires and edges that are mapped to the
original mesh.
This change enables mapping data in regular Mesh extraction. This
can also be used for better drawing of the normal overlay.

The default face set color is white, so we can skip drawing the default
face set. This allows to enable again the optimization of not drawing
overlays in nodes where the mask is empty.
This will still slow down the viewport when a new face set is created
for the whole mesh or when inverting the mask, like in previous
versions.
I also renamed the function to make more clear that now it is checking
for both mask and face sets.

This is not the background of the viewport, it is a transparency

When in editmode faces can be hidden, but in object mode these faces are
still visible. The flag if a face was hidden in edit mode is stored in
object mode, but should not be used.

Only the volume drawing part is really finished and exposed to the user. Hair
plugs into the existing hair rendering code and is fairly straightforward. The
pointcloud drawing is a hack using overlays rather than Eevee and workbench.
The most tricky part for volume rendering is the case where each volume grid
has a different transform, which requires an additional matrix in the shader
and non-trivial logic in Eevee volume drawing. In the common case were all the
transforms match we don't use the additional per-grid matrix in the shader.

This check box alters how weights are displayed and painted,
similar to Multi Paint, but in a different way. Specifically,
weights are presented as if all locked vertex groups were
deleted, and the remaining deform groups normalized.
The new feature is intended for use when balancing weights within
a group of bones while all others are locked. Enabling the option
presents weight as if the locked bones didn't exist, and their
weight was proportionally redistributed to the editable bones.
Conversely, the Multi-Paint feature allows balancing a group of
bones as a whole against all unselected bones, while ignoring
weight distribution within the selected group.
This mode also allows temporarily viewing non-normalized weights
as if they were normalized, without actually changing the values.

NOTE: While most of the milestone 1 goals are there, a few smaller features and
improvements are still to be done.
Big picture of this milestone: Initial, OpenXR-based virtual reality support
for users and foundation for advanced use cases.
Maniphest Task: https://developer.blender.org/T71347
The tasks contains more information about this milestone.
To be clear: This is not a feature rich VR implementation, it's focused on the
initial scene inspection use case. We intentionally focused on that, further
features like controller support are part of the next milestone.
- How to use?
Instructions on how to use this are here:
https://wiki.blender.org/wiki/User:Severin/GSoC-2019/How_to_Test
These will be updated and moved to a more official place (likely the manual) soon.
Currently Windows Mixed Reality and Oculus devices are usable. Valve/HTC
headsets don't support the OpenXR standard yet and hence, do not work with this
implementation.
---------------
This is the C-side implementation of the features added for initial VR
support as per milestone 1. A "VR Scene Inspection" Add-on will be
committed separately, to expose the VR functionality in the UI. It also
adds some further features for milestone 1, namely a landmarking system
(stored view locations in the VR space)
Main additions/features:
* Support for rendering viewports to an HMD, with good performance.
* Option to sync the VR view perspective with a fully interactive,
regular 3D View (VR-Mirror).
* Option to disable positional tracking. Keeps the current position (calculated
based on the VR eye center pose) when enabled while a VR session is running.
* Some regular viewport settings for the VR view
* RNA/Python-API to query and set VR session state information.
* WM-XR: Layer tying Ghost-XR to the Blender specific APIs/data
* wmSurface API: drawable, non-window container (manages Ghost-OpenGL and GPU
context)
* DNA/RNA for management of VR session settings
* `--debug-xr` and `--debug-xr-time` commandline options
* Utility batch & config file for using the Oculus runtime on Windows.
* Most VR data is runtime only. The exception is user settings which are saved
to files (`XrSessionSettings`).
* VR support can be disabled through the `WITH_XR_OPENXR` compiler flag.

This has no user visible impact yet since smoke volumes only support a fixed

For GPU shader compilation, volume grids are now handled separately from
