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.

A few thank you's:
* A huge shoutout to Ray Molenkamp for his help during the project - it would
have not been that successful without him!
* Sebastian Koenig and Simeon Conzendorf for testing and feedback!
* The reviewers, especially Brecht Van Lommel!
* Dalai Felinto for pushing and managing me to get this done ;)
* The OpenXR working group for providing an open standard. I think we're the
first bigger application to adopt OpenXR. Congratulations to them and
ourselves :)
This project started as a Google Summer of Code 2019 project - "Core Support of
Virtual Reality Headsets through OpenXR" (see

Owner of filelisting job was changed, without proper update of all
access/usages of that owner to reach the job, leading to failure of
timer removal from the WM, and attempt to double-free the job...
Caused by rB2c4dfbb00246ff.
EasingType was implemented rBdaccaa713b6e for the GraphEditor (but never
made it to the Dopesheet). If you can select Easing Mode in the
DopeSheet, then you should also be able to select the associated Easing
Type.
Thanks @lichtwerk for the initial implementation.

Caused by the introduction of UDIM (rBc30d6571bb47).
We need to make sure the tiles ImageUser is set up correctly [especially
the framenr], otherwise BKE_image_acquire_ibuf() and friends will fail
to find the correct ImBuf.
Also instead of initializing a minimal BKE_imageuser_default, now use
an appropriate ImageUser if avaliable and pass this around (instead of
just the tile_number). 2D painting can reuse the Image Editor ImageUser,
for 3D painting we still rely on a default ImageUser in most places, but
at least set the framenr correctly].
This also fixes crashes when doing image operations such as inverting or
resizing on images in a sequence in the Image Editor.
This also fixes color sampling (S) from the 3DView going wrong for image
sequences (would fallback to OpenGL sampling because an ImBuf could not
be found).

This commit is a full refactor of the grease pencil modules including Draw Engine, Modifiers, VFX, depsgraph update, improvements in operators and conversion of Sculpt and Weight paint tools to real brushes.

Currently, this change does not bring functional changes.
But it is necessary to extend the use of the snap system for gizmos,
since, after a Undo, the `depsgraph` pointed by the `snap_context`
has its memory invalidated.

The old convention was easy to confuse with ScrArea.
Part of https://developer.blender.org/T74432.
This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.

There's a chance that this causes some issues becaue in some cases we
change from getting the window from context to getting it from somewhere
else.
This patch will make use of the eDrawType where it was used as a
variable or parameter name. The eObjectDrawType was renamed to eDrawType
as it is also used by `View3DShading.type`.
Motivation the functions get 3 different kind of flag parameters (ImBuf,
DrawType, OffscreenRendering) the naming of the flags were not clear,
leading to mistakes and unnecessary time spend debugging.
- Use 'int' for counters instead of short.
- Use 'bool' instead of a counter when only a change is being detected.
- Use typed enum for keying set flags.
- Include in comments when a negate error code may be returned.
- Split 'verify_fcurve' into two functions:
ED_action_fcurve_ensure which adds the f-curve if needed.
ED_action_fcurve_find which returns NULL when not found.
Callers of ED_action_fcurve_find had unused 'group'
argument which has been removed.
- Rename verify_adt_action to ED_id_action_ensure
It had an argument to add data which was always true,
remove this instead of splitting in into a separate function.

The redo panel does not consider the position of the mouse.
So it is not possible to know the direction to redo the operator.
The solution is to add a new `direction` parameter that can be
saved and used for redo.

NOTE: This change shouldn't have any visible effect. It's just the
first (easiest) step towards decoupling gizmo redraws from viewport
redraws.
We currently redraw the entire region whenever a gizmo needs redrawing,
which would be nice to avoid in the future, see T73198. The first step
towards this would be having a separate tag for them, which is what
this patch implements.
The term "editor-overlays" was chosen because for the forseeable future,
we'll also have to redraw non-gizmo overlays in-between drawing 3D and
2D gizmos. Namely annotations.
