When Blender is started in fullscreen mode from the command line,
or if the fullscreen state is saved in the startup file, all temporary windows
will also open in fullscreen mode. When closing the fullscreen File Browser,
Blender would either crash or parent window becomes black.
This does not happen if the Blender switches to full screen manually.
`NSWindowCollectionBehaviorFullScreenPrimary` should be set for windows that
can enter full-screen mode. Otherwise macOS will turn the wrong window into
full-screen.

Steam just released a SteamVR update with OpenXR Developer Preview
support:
https://steamcommunity.com/games/250820/announcements/detail/2396425843528787270.
Once SteamVR is set up for OpenXR (see link above), it works with
Blender "out of the box", thanks to OpenXR!
We have to apply the sRGB transform workaround for SteamVR though,
otherwise it renders way too dark. Done in the next commit.
Note that AMD users may still only see a pink screen, because the
OpenGL-DirectX compatibility fails. I will check on a fix again.
For SteamVR on Linux we may have to wait for until it supports OpenGL
rendering for OpenXR. Alternatively, we *could* add initial Vulkan
support at Ghost level and use Vulkan<->OpenGL interoperability
extensions, Monado uses these as well.
Windows only workaround. I'll have to investigate Linux separately.
Steam's OpenGL compatibility is still new and doesn't work for us yet
(neither does it for standard OpenXR examples from what I've heard and
seen myself). We can work around that by falling back to our DirectX
compatibility layer.
Note that this DirectX compatibility still doesn't work for some
systems, see T76082.
Implementation note: Since the graphics binding extensions have to be
enabled before we can find out which runtime is in use (e.g. SteamVR vs.
Oculus, etc), we can now enable multiple graphics binding extensions but
settle for a single one to use later.
Once the SteamVR OpenGL backend works, we can remove this workaround
again.
Fixes T78267.
Latest SteamVR OpenXR updates brought OpenGL support, but only with sRGB
buffers. I think for DirectX it's the same now.
It's not a big issue for us to use sRGB buffers, so that's what I will
do for now. That way we shouldn't need hardcoded exceptions for specific
runtimes that don't transform linear buffers correctly.
When closing the File Browser window after making it fullscreen, Blender would
either crash or all windows would disappear, with no obvious way to bring them
back.
The "fix" is to not allow fullscreen for File Browsers (or any future "dialog"
windows), but only maximizing. From what I can tell that's how secondary
windows are supposed to work on macOS. What we previously did seemed like
something macOS doesn't handle cleanly, and I didn't find a simple way to do so
on our side.
With the Oculus runtime, the VR session would freeze when taking off the HMD
and putting it back on. This was caused by the deletion of graphics resources
too early in the OpenXR state machine, at least for Oculus.
The resources will now only be freed once the session is actually destroyed.
Also fixes an issue where it wasn't possible to stop the session via the UI
when the HMD was taken off.

This reverts commit 1a3928f33c and 1a3928f3. This is not working stable
with some Wintab implementations, so reverting for now. This leaves only
the Windows Ink changes for 2.83.
Some Wintab drivers report a zero length queue, this causes an unplanned never ending loop.

Rather than using the last state of the tablet, we now query the history of

All DirectX management happens on Ghost level now, higher level code can
just assume everything is OpenGL (except of the upside-down drawing that
still needs to be done for DirectX). This is similar to how the
metal-layer is hidden outside of Ghost.
The Ghost-XR graphics binding for DirectX is responsible for managing
the DirectX compatibility now.
Removing the GHOST_kKeyUnknown check from processKeyEvent() produces
epeated unknown key events whenever a modifier key is held down, due
to the way ghost uses GHOST_kKeyUnknown as a filter value for modifier
key events.

Events for keys specific to certain keyboard layouts unknown to Blender

There is no need to have another font embedded in the Blender executable, we
can assume the bundled font exists. In the future we may provide a fallback
if the font specified by the user in the preferences is missing a character,

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:

* 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

Extends Ghost to include an abstraction for OpenXR, which I refer to as
Ghost-XR. Such an API is the base for the following commit, which introduces VR
support to Blender.
Main features:
* Simple and high-level interface for Blender specific code to call.
* Extensible for muliple graphics backends, currently OpenGL and a DirectX
compatibility layer are supported.
* Carefully designed error handling strategy allowing Blender to handle errors
gracefully and with useful error messages.
* OpenXR extension and API-layer management.
* OpenXR session management.
* Basic OpenXR event management.
* Debug utilities for Ghost-XR and OpenXR

- Keymap items now have 'repeat' boolean which can be set
to make keymap items respond to key repeat events or not.
- Support for X11 & WIN32 (not macOS currently).
This allows for the possibility to perform actions while a key is held
and finish the action upon release.
Thanks to @Severin for review and WIN32 support.
Adds a minimal DirectX 11 Ghost context, plus some shared DirectX-OpenGL
resource interface using the NV_DX_interop2 WGL extension. From what I
know, this should be available on modern GPUs. If not, it should fail
gracefully.
There should be no user visible changes at this point.
Needed for DirectX-only OpenXR platforms (e.g. Windows Mixed Reality). I
heard there are other use-cases as well though.
It's known that this currently fails on some AMD systems, but that seems
to be fixable.
Most of this comes from the 2019 GSoC project, "Core Support of Virtual
Reality Headsets through OpenXR"
