Some doc-strings were skipped because of blank-lines between
the doc-string and the symbol and needed to be moved manually.
- Added space below non doc-string comments to make it clear
these aren't comments for the symbols directly below them.
- Use doxy sections for some headers.

Apply a local-workaround instead of adding support for this use-case
since pre-selection isn't the intended purpose of gizmos.
This also resolves a glitch where poly-build and loop cut would
briefly show loop-cut or poly-build pre-selection after transforming.
See gizmo_preselect_poll_for_draw note for more details.
Error introduced in rB69d6222481b4 and partially fixed in rB24310441ddc8.
When gizmo was turned on but the scene has more than one 3D viewport, one of them the snap cursor did not appear.
Operations such as erasing with occlusion and drawing on the surface
require reading the depth buffer.
However, this is being done with minimal efficiency.
Currently, to read the depth corresponding to each point of the new stroke,
a ReadPixel is called to send a message to the GPU and read the depth of
the corresponding pixel in the VRAM.
The communication between GPU and CPU is known to be a slow operation so
it is good to be avoided.
Therefore, save the entire depth buffer in a cache to be read directly
from the RAM.
(Also the `ED_view3d_autodist_depth` and `ED_view3d_autodist_depth_seg` have
been removed since they are no longer used).

The drag and drop feature of objects in 3D View has been modified to include:
- Snap the object being dragged.
- Visual feedback through a box and the placement tool grid.
Maniphest Tasks: T90198
Differential Revision: https://developer.blender.org/D12912
Make the snap system consistent with the placement tool and leak-safe.
**Changes:**
- Store `SnapCursorDataIntern` in a `static` variable;
- Initialize (lazily) `SnapCursorDataIntern` only once (for the keymap).
- Move setup members of `V3DSnapCursorData` to a new struct `V3DSnapCursorState`
- Merge `ED_view3d_cursor_snap_activate_point` and `ED_view3d_cursor_snap_activate_plane` into `state = ED_view3d_cursor_snap_active()`
- Merge `ED_view3d_cursor_snap_deactivate_point` and `ED_view3d_cursor_snap_deactivate_plane` into `ED_view3d_cursor_snap_deactive(state)`
- Be sure to free the snap context when closing via `ED_view3d_cursor_snap_exit`
- Use RNA properties callbacks to update the properties of the `"Add Primitive Object"` operator
Move most of the gizmo snap and placement code to `view_cursor_snap.c`.
Simplify and extend the snap API.

This patch allows dropping material assets from material slot under the mouse
cursor. Before this change the material slot had to be hand-picked from the
properties panel.
For consistency it is chosen to do this in any shading mode as the tooltip shows
what is exactly going to happen during release.
The feature also works for other object types than Meshes as it uses the drawn surface on the
GPU to detect the material slots. Performance of this patch has been tested with AMD GCN3.0
cards and are very responsive.

The depth cache (located in `RegionView3D::depths`) is used for quick
and simple occlusion testing in:
- particle selection,
- "Draw Curve" operator and
- "Interactive Light Track to Cursor" operator,
However, keeping a texture buffer in cache is not a recommended practice.
For displays with high resolution like 8k this represents something
around 132MB.
Also, currently, each call to `ED_view3d_depth_override` invalidates
the depth cache. So that depth is never reused in multiple calls from
an operator (this was not the case in blender 2.79).
This commit allows to create a depth cache and release it in the same
operator. Thus, the buffer is kept in cache for a short time, freeing
up space.
No functional changes.
This resolves a long standing bug in edge selection
(picking, circle, box & lasso).
Now when one of the edges vertices fails to project into screen space,
the edge is clipped by the viewport to calculate an on-screen location
that can be used instead.
This isn't default as it may be important for the on the screen location
not to be clipped by the viewport.
When projecting into screen space Z value isn't always needed.
Add 2D projection functions, renaming them to avoid accidents
happening again.
- Add GPU_matrix_project_2fv
- Add ED_view3d_project_v2
- Rename ED_view3d_project to ED_view3d_project_v3
- Use the 2D versions of these functions when the Z value isn't used.
Now `ED_view3d_backbuf_depth_validate`, `ED_view3d_draw_depth` and
`ED_view3d_draw_depth_gpencil` are unified in `ED_view3d_depth_override`.
This new function replaces `ED_view3d_autodist_init`.
Also, since `ED_view3d_depth_update` depends on the render context, and
changing the context is a slow operation, that function also was removed,
and the depth buffer cached is now updated inside the new unified drawing
function when the "bool update_cache" parameter is true.
Finally `V3D_INVALID_BACKBUF` flag has been renamed and moved to
`runtime.flag`.

Object previews are really helpful for visual data-block selection, like asset
browsing. Having them be generative should also be quite handy and should work
well enough in many, if not most cases.
What this does is simple:
* Place the object (actually a deep copy of it, for thread safety) in a virtual
.blend into an empty scene/view-layer.
* Add a camera, point it towards the front of the object, assuming that means
pointing towards its +Y axis.
* Use "Camera Fit Frame to Selected" logic to put the object into frame.
* Create a threaded off-screen render.
Of course, such an automatic preview will not work in all situations. E.g. it
currently does a bad job capturing a single plane. We could add options for
more advanced automatic previews, but probably custom previews is more
important, which I committed already (812ea91842).

Since the depth can't be properly visualized in 3D, display a 2D so
it's possible to to tell the depth from the cursor motion.
The behavior of the incremental snap did not take into account the
relative dimensions of the window, which resulted in a different behavior
if the area height was greater than the width.
This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),

The was caused by 8b347fc2cd as the old BONESEL_NOSEL flag
handled the -1 case (used for none).
Instead of checking for -1, remove these elements from the array
as selection code makes decisions based on the number of hits detected.
When editing a complex curve is very annoying to have all handles at a time. Also, this is a requirement for the current GSoC Edit Grease Pencil using curves.
I have seen that this improvement can be used in any other area of blender, so I have decided to publish the option in the overlay panel..

Due to recent changes clicks in the node editor would trigger a
depsgraph update resulting in too many redraws. This patch limits
the updates to when workbench shown in texture mode in any visible
screen.
There are still cases where too many updates are created. For example when
there are a Cycles render viewport and a Workbench texture viewport on the
same screen.
This fix is meant as a workaround. The actual fix should add a mechanism
to the depsgraph and the viewports should check if they need to be redrawn.
