Gizmos that contain 3D parts, like the rounded lines of the "Rotate"
gizmo, have a fairly small hit size that make it hard to grab with a
tablet pen. This PR just increases the radius around the pointer
position while using a pen.

Some OpenXR platforms do not support OpenGL or Vulkan. To support these
platforms we use a bridge. Blender still renders in OpenGL/Vulkan, but
will copy the render result into a D3D11 swapchain.
OpenGL doesn this by importing the D3D11 swapchain into the OpenGL
context and perfor OpenGL calls to update the swapchain. However for
vulkan that could lead to construct 3 context for OpenXR
- Blender GPU Context
- OpenXR D3D Context
- New context that imports the Blender render result and the OpenXR
Swapchain image and copies them.
Due to Direct3D limitations importing into a vulkan context has known
issues (driver + extensions). Secondly we are not sure if we are running
on the same device as the OpenXR swapchain. The solution provided with
this PR is to only support CPU data transfers.
**SteamVR using d3d bridge**
SteamVR normally would use the Vulkan binding. But by changing the binding
priority in code you can make it select the D3D bridge.

Part of #82877
When drawing specialized cursors for the different paint modes via the
`wmPaintCursor` draw callback, tablet tilt direction is unavailable to
use to customize the drawing for the user.
To enable this functionality, this commit adds the `x_tilt` and `y_tilt`
data read while processing MOUSEMOVE events to the `eventstate` variable
so it can be used by consuming functions.

Even though the default startup already has `Trusted Source` and
`Auto Run Python Scripts` off by default, when resetting their values
to default (right click, Reset to Default) they would be turned on.
It was simply missing explicitly setting this off by default.

Failure to refresh the highlighted gizmo meant that clicking
on a highlighted gizmo would attempt to activate it even though
it's poll function failed - which crashed in this case.
Resolve the common-case by ensuring a call to refresh the gizmo-map
causes the event system to re-evaluate the highlighted gizmo,
even if the cursor doesn't move.
Since it's still possible the call to "refresh" the gizmo is missed,
gizmo_tweak_invoke now checks the gizmo-groups poll succeeds with an
assert and early return if it doesn't. This would have prevented the
crash although the highlighted-gizmo still won't be reset - causing
the cursor to display as if it's over a gizmo until it's moved.
`radial_control_modal` would only actually update the target property
(via `RNA_property_update`) for the "standard" ways of confirming
(`LEFTMOUSE`, `EVT_PADENTER`, `EVT_RETKEY`).
When using "release_confirm" however, that was skipped, so added the
`RNA_property_update` now.

Current implementation uses a CPU roundtrip to transfer render result
to the Xr Swapchain. This PR adds support for sharing the render result
on Linux systems by using file descriptors.
To extend this solution to win32 or dx handles can be done by extending
the data transfer modes, register the correct extensions. When not
using the same GPU between Blender and OpenXR the CPU roundtrip
will still be used.
Solution has been validated with monado simulator and seems to be as
fast as OpenGL.
Performance can be improved by using GPU based synchronization.
Current API is limited as we cannot chain the different renders and
swapchains.

GPU_DEPTH_NONE leads to issues with Intel GPU drivers on Windows
where camera gizmos cannot be shifted. glGetQueryObjectuiv for
GL_SAMPLES_PASSED seems to return zero in all cases.
This might be due to undefined behavior of OpenGL when the depth
test is disabled and rendering to a depth render target-only
framebuffer. Using GPU_DEPTH_ALWAYS fixes the issue.

`win->ime_data` could be non-null when it's read from a file, and
subsequent dependence of this value would crash on interface handlers.
Now always clear it when ghost window is ensured after reading the file.
The actual reset is put in `wm_window_ensure_eventstate`, since it's
also conceptually a part of "event state".

Use enum types for event modifier and types,
`wmEventModifierFlag` & `wmEventType` respectively.
This helps with readability and avoids unintended mixing with other
types. To quiet GCC's `-Wswitch` warnings many `default` cases needed
to be added to switch statements on event types.

MacOS generally uses mouse cursors we specifically made for that
platform. But in some cases, like WM_CURSOR_WAIT, the OS does not have
an equivalent and we don't have a platform-specific one. So it then
uses of of our base custom cursors. This type of cursor is always
enlarged on Mac high-DPI displays like Retina. So no need to ever
supply larger versions of this type of cursor as it will just get
huge.

Part of incoming refactors in interface layout c++ code, this enables

The Blender config.ocio does not have any rules, but custom ones can.
The default file rule is ignored if default_byte or default_float roles
exist. These roles are Blender specific, so would not be found in a typical
OCIO config. But when they are set appropriately, they help provide better
default guesses than what is possible with standard OCIO rules.

The Blender's VkInstance cannot be shared with OpenXR VkInstance. The
reason is a chicken and egg problem where OpenXR needs to be started
before Vulkan. OpenXR can add special vulkan specific requirements
(instance&device) that are only available when the user starts an OpenXR
session.
The goal implementation is to share memory between both instances using
[VK_KHR_external_memory](https://registry.khronos.org/vulkan/specs/latest/man/html/VK_KHR_external_memory.html) and related extensions. However this seems
to be a bridge to far as a initial step. Reason: There are not that many
samples/ guides and documentation to be found to handle the workflow that
we require. We want to do a smaller step by step approach to gain the needed
knowledge.
For that reason this PR does the most stupidest thing that can be done to
share memory between instances. Download the render result to CPU RAM share
the host pointer with the OpenXR instance which copies it to the swap chain.
Also the synchronization is done using wait idle commands.

**Gaining knowledge**
- Experiment with `VK_KHR_external_memory_host` extension for uploading vertex buffers (not related to OpenXR).
- Import host pointer with `VK_KHR_external_memory_host`. This reduces the additional
memcpy on OpenXR side.
- Export host pointer from Blender side from a mappable buffer.
- Replace host pointers with fd/dmabuf/winhandle
- Remove mappable buffer.

Even though the doc-string notes that they're only used for
function parameters, it looks as if they might be used for
`wmEvent::modifier` and are exposed in a prominent location.
Remove the flags & replace them with a macro that bit-shifts the
existing modifier values which is more clearly intended to be used
with `KeyMapItem_Params`.
Ref !136539
Add support for a 5th modifier key called "hyper",
this is a modifier supported on Wayland & X11 although
other platforms could support an additional modifier too.
Both GNOME and KDE can map CapsLock to Hyper.
Other compositors can use the XKB_DEFAULT_OPTIONS environment variable.
This allows users to have an additional modifier for their own use
that doesn't conflict with other keys.
Ref !136340
Rename to be more consistent with other Blender keymaps, as well as the
naming convention used in "View Type."
- "SequencerCommon" -> "Video Sequence Editor"
- "SequencerPreview" -> "Preview"
- "Sequencer Timeline Tool" -> "Sequencer Tool"
- "Sequencer Preview Tool" -> "Preview Tool"
There is versioning in place to make sure custom keyconfigs keep working.
Once #131102 goes through, if we would like to rename the "Sequencer"
view type to "Timeline" or "Sequencer Timeline," then we can make the
necessary changes here too.

Some of the existing logic checked that modifiers were KM_MOD_HELD,
other logic checked the value wasn't KM_NOTHING or KM_ANY.
Simplify checks by comparing against KM_MOD_HELD in all cases
as this won't be set to other values.
- Document values to use for modifiers in code-comments.
- Only compare modifier values with KM_ANY/NOTHING/MOD_HELD.
- Use smaller integer sizes where possible.
- Manually check over all direct calls to operator callbacks
ensuring the result isn't assigned to an int.
- OPERATOR_RETVAL_CHECK() now fails unless a wmOperatorStatus is used.
- Check the return values of direct calls to callbacks.
- Remove invalid check for the return value of rna_operator_check_cb.
- Use the variable name `retval` as it's most widely used.
- Move the assignment of `retval` out of the `if` statement in
sculpt/paint operators because it prevents assigning the result
`const` variable.
Callbacks: exec invoke & modal now use a typed enum wmOperatorStatus.
This helps avoid mistakes returning incompatible booleans or other
values which don't make sense for operators to return.
It also makes it more obvious functions in the WM API are intended
to be used to calculate return values for operator callbacks.
Operator enums have been moved into DNA_windowmanager_enums.h
so this can be used in other headers without loading other includes
indirectly.
No functional changes expected.

Part of #134755 / #134766.
Adds options to the new Import Settings popover (added in 7a6beb65f4)
to toggle collection instancing for dragging in collections. It can be
toggled separately for linking and appending, since it's typical to use
instancing for linking, but not appending (current default, also with
this change).
Previously, toggling collection instancing was only possible via the
Adjust Last Operation panel but this wasn't obvious, many people were
not aware. Adding this option based on feedback by the Blender Studio.

Regular "Save As" does not set "incremental" property, either true or
false, which results in a warning message. This PR just handles the

Hovering over UI items will pop up a tooltip hint if you are perfectly
still. This is easy when using a mouse since it is resting on a
surface. But with a tablet pen you are holding it off the surface so
absolute stillness is difficult. This PR allow a small amount of
movement. So unsteady or slow movement will still pop up the hint.
