This has some advantages over operator search:
- Some operators need options set to be usefully accessed.
- Shows key bindings to access menus
(for actions that don't have key bindings themselves).
- Non operator actions such as check-boxes are also shown.
- Menu items can control execution context, using invoke or execute
where appropriate so we can control how the operator runs.
Part of the design task T74157.
This can be tested using the 'Experimental' preferences section
or selected in the key-map editor.
Mpving utils from idcode to idtype proved to be somewhat painful for
some reasons, but now all looks good.
Had to add a fake/empty shell for the special snowflake too,
`ID_LINK_PLACEHOLDER/INDEX_ID_NULL`...
Both the MS headers and blender headers define the HKEY
which gives all kind of inclusion order issues.
This diff renames all *KEY constants to EVT_*KEY to resolve
this conflict.

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.

'Private' can be a rather confusing term, especially when considering
its meaning in programming languages.
So now root node trees and master collections are 'embedded' IDs
instead.
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.
`invoke_props_dialog` and `invoke_popup` had a width and a height field. The height field was ignored as the height is determined based on the content. This change removes the field from the BPY + WM_api

Using a struct here allows to change given parameters to the callbacks
without having to edit all callbacks functions, which is always noisy
and time consuming.
When text drawing is disabled in the viewport the color of the sculpt
brh is set to the last used one. In th Light theme this is black what
makes it totally not visible.
This change will render the brush text using `TEXT_HI` as this is the
last one set when the text overlay is on.
event_system.c has been collecting a lot of different functionality,
move generic query/access functions into their own file,
since these are used by operators and other parts of the windowing code
and aren't part of low level event handling.
Also move public last-property API to wm_operators.c.
Previously the alpha was hardcoded to 0.7. Now it is possible to control
the cursor alpha by changing the alpha color of the cursor color
property. New alpha default is 0.9. This, with the new saturated colors,
should make the cursor more visible on highdpi screens.
I also removed the cache location preview as it is too visible right now
with the new alpha and color values.

When introducing "drag-all-selected" support all over Blender, we
figured this wouldn't work well with the Graph Editor
selection/transform behavior.
Hence, William and I worked on the following changes, although we used
this chance to improve the behavior in general too.
For more info see T70634.
* Handles now always move with the key, regardless if they are selected
or not.
* Selecting the key doesn't select the handles anymore, their selection
is separate.
* Multiple keys and handles can now be dragged.
* Dragging a handle moves all selected handles **on the same side**.
* Tweak-dragging any handle can never affect any keyframe location,
only handles.
* G/R/S should behave as before.
* Changing the handle type with a key selected always applies the change
to both handles.
* Box selection with Ctrl+Drag now allows deselecting handles (used to
act on entire triple only).
* Box selection //Include Handles// option now only acts on visible
handles, wasn't the case with Only Selected Keyframes Handles enabled.
* Box selection //Include Handles// is now enabled by default in all
bundled keymaps.
The changes have been tested for some days by the animators here in the
Blender Animation Studio. Some changes are based on their feedback.
Also, this improves/adds comments for related code.

Steps to recreate were:
* Open a Node Editor, add some nodes
* Save the file
* Select all nodes (A)
* Save it again, but with Ctrl+S
* Try to select an already selected node
It's supposed to deselect other nodes now, but for as long as the report
banner is shown in the status-bar ('Saved "foo.blend"'), this doesn't
work.
Also happened in the VSE, Dopesheet, NLA or everywhere else we recently
added drag-all-selected support to.
Issue was in there since 2.80. Basically the timer event sent by the
report banner broke assumptions in the selection operator.
Hope this fix doesn't have any side effects. Checked with Bastien
(initial author of this logic), but seems things are fine.
Based on work by Bastien and Brecht in the Node Editor, this adds more
generalized support for selecting items so that click+drag actions on
items (nodes, makers, dopesheet keys, etc.) works as wanted.
Note that this only adds the barebones to support this in other editors,
it's not used yet (will be done in followup commits).
The behavior is supposed to work as follows:
* Clicking an unselected item immediately selects it, and deselects
other items (doesn't wait for release events).
* Click+drag on an unselected item immediately selects it, deselects
others and drags it in one go (don't require selecting it first!).
* Click+drag on a selected item won't change the selection state (and
won't send an undo push) and start dragging all selected items as soon
as the drag event is recognized.
* Clicking on a selected item will still deselect others, but that will
only happen on mouse release, when we know the intention is not to drag
the item.

This commit introduces the following changes:
- Invert the direction of the brush strength WM control. It was working in the opposite direction to any other control in Blender. Now dragging to the right increases the strength.
- Increase the alpha of the cursor
- Remove the font shadow of the numbers in the WM control. It was adding too much visual noise when rendered on top of the brush alpha
- Add a second circle to preview the strength in the cursor
- Increase the resolution of the cursor circles. Now they look smooth even when working with large brush sizes.
- Add a line preview to display the brush curve
- Don't offset the cursor preview when changing size and strength

NodeTree structures of materials and some other data blocks are
effectively node group datablock objects that are contained inside
the parent block. Thus, direct references to them are only valid
while blender is running, and are lost on save.
Fix Copy As New Driver to create a reference that goes through
the owner datablock, by adding a new ID flag to mark private
pseudo-datablocks.
Also fix functions that return full paths to structures and
properties, e.g. used in python tooltips. Functions for paths
from ID to struct or property can't be changed because of

The old layout of `PointerRNA` was confusing for historic reasons:
```
typedef struct PointerRNA {
struct {
void *data;
} id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
This patch updates it to:
```
typedef struct PointerRNA {
struct ID *owner_id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
Throughout the code base `id.data` was replaced with `owner_id`.
Furthermore, many explicit pointer type casts were added which
were implicit before. Some type casts to `ID *` were removed.

This change ensures that operators which needs access to evaluated data
first makes sure there is a dependency graph.
Other accesses to the dependency graph made it more explicit about
whether they just need a valid dependency graph pointer or whether they
expect the graph to be already evaluated.
This replaces OPTYPE_USE_EVAL_DATA which is now removed.
Some general rules about usage of accessors:
- Drawing is expected to happen from a fully evaluated dependency graph.
There is now a function to access it, which will in the future control
that dependency graph is actually evaluated.
This check is not yet done because there are some things to be taken
care about first: for example, post-update hooks might leave scene in
a state where something is still tagged for update.
- All operators which needs to access evaluated state must use
CTX_data_ensure_evaluated_depsgraph().
This function replaces OPTYPE_USE_EVAL_DATA.
The call is generally to be done in the very beginning of the
operator, prior other logic (unless this is some comprehensive
operator which might or might not need access to an evaluated state).
This call is never to be used from a loop.
If some utility function requires evaluated state of dependency graph
the graph is to be passed as an explicit argument. This way it is
clear that no evaluation happens in a loop or something like this.
- All cases which needs to know dependency graph pointer, but which
doesn't want to actually evaluate it can use old-style function
CTX_data_depsgraph_pointer(), assuming that underlying code will
ensure dependency graph is evaluated prior to accessing it.
- The new functions are replacing OPTYPE_USE_EVAL_DATA, so now it is
explicit and local about where dependency graph is being ensured.
This commit also contains some fixes of wrong usage of evaluation
functions on original objects. Ideally should be split out, but in
reality with all the APIs being renamed is quite tricky.
Fixes T67454: Blender crash on rapid undo and select
Speculation here is that sometimes undo and selection operators are
sometimes handled in the same event loop iteration, which leaves
non-evaluated dependency graph.
