Outliner would frame the armature object instead of the bone if the bone
was on a hidden armature layer.
Similar to issues reported in e.g. T58068 and T80464, this is due to the
fact that `BKE_pose_channel_active` always checks for the armature layer
(and returns NULL if a bone is not on a visible armature layer).
Now propose to make this layer check **optional** (and e.g. from the
Outliner be more permissive). This also introduces
`BKE_pose_channel_active_if_layer_visible` which just wraps
`BKE_pose_channel_active` with the check being ON.

bda9e4238a07a72c26598ea9025e00f6ca896750 changed smooth-view
not to redraw when there were no changes made.
Redrawing is needed for repositioning the cursor.
Subscribe to changes to the 3d cursor to ensure all view ports
are updated (not just the current one).

Float precision issues cause the `ED_view3d_win_to_3d_on_plane` to return
a value even when the view ray is parallel to the plane.
A more general solution might be desired in this case, as other areas that
use `ED_view3d_win_to_3d_on_plane` might have the same problem.
For now, just work around the problem for the snap cursor.
|
|
There is an apparent compiler bug here, tweak the code to avoid it. This did
not affect official builds as we were still using Xcode 12.

|
`ED_view3d_win_to_3d_on_plane` does not use the `clip_start` and
`clip_end` values of the scene, so the `do_clip` option can be misleading
especially in the orthographic view where the `clip_start` is negative.
For now, don't use the `do_clip` option in orthographic view.

`g_data_intern.state_default.gzgrp_type` is a very specific member and
cannot be set to default.

This is very old and is unlikely to be useful in the near future.

The default snap behavior to perform on tools and cursors is to the
final geometry and not edited geometry.
In snapping to edited geometry, there are some specific behaviors that
are not convenient in some cases. For example the general occlusion
test of X-Ray geometries during dragdrop.
This fix also resolves a regression for tools like measure and placement
that were also ignoring the snap to face in x-ray mode.

Bug introduced in {rBaa0ac0035a0d}.
The invalid depth fallback was changed to `FLT_MAX` in order to match the
annotation and gpencil operations.
This broke the `Interactive Light Track` operator which invalidates the
operation if the depth value is `1.0f`.
The chosen solution was to change the value tested in the annotation and
gpencil operations.

The old code did not work when there were multiple ids with
the same name (which can happen when ids are linked in).
The solution is to use the session ids instead. Those are different
even when two ids have the same name.

This patch implements part of what was stated in {T66484}, with respect to `Base Point`.
## Introduction
The snapping feature of the transform tools has a variety of applications:
- Organization of nodes.
- Positioning of frames in precise time units.
- Retopology with snap to face
- Creation of armatures with bone positioning through the snap to volume
- Precise positioning of 3D or 2D objects in the surrounding geometry (CAD modeling)
The goal of this document is to make it more powerful for precision modeling and still supporting the old use cases without extra complexity.
The main topic addressed here is the introduction of a **interactive mode for setting a snap source** (See terminology).
## Terminology
* **Snap Source**: 3d coordinate * we want to snap from. (Currently defined by the `Snap With` options: `Closest`, `Center`, `Median` and `Active`).
* **Snap Target**: 3d coordinate* we want to snap to. (Vertices, Edges, Faces, Grid...)
## Interactive Mode for Editing a Snap Source
Currently the fixed snap point can only be obtained through the `Snap With` options. So it's a little tricky for the user to define a snap source point having so much geometry on an object.
Because of this, the user needs to resort to impractical solutions to get a point in the geometry.
See example of an impractical use:
{F11714181, layout=left, width=960, alt="The user used the cursor (which can be snapped) to choose the snap origin point."}
The user used the cursor (which can be snapped) to choose the snap source point.
While it is possible to work around this current limitation, it is important to reduce the number of steps and allow the user to set a snap source point through an optional interactive mode during a transformation.
The proposed solution is to be able to move the current snap source point through a modal modifier activated with a key (eg. B).
The snap source point can thus "snap" to the elements in the scene (vertex, mid-edge, Lamp, …) during this mode.
{F9122814, layout=left, width=960, alt="Base Point Snap, example of transform operation via the shortcut (not the tool). After pressing g and the snap base change shortcut (e.g., shift + ctrl) the user set the base point. The base point is then visible until the end of the operation. The z axis constrains the final position."}
## Implementation Details
- The feature will only be available in 3D View.
- The feature will only be available for `Move`, `Rotate` and `Scale` transform modes.
- The snap source editing will be enabled with a single click on the modifier key (B).
- Having a snap point indicated, the new snap origin point will be confirmed with the same buttons that confirms the transformation (but the transformation will not be concluded).
- The snap source editing can be canceled with the same key that activated it (B).
- If the transformation is done with "release_confirm" (common for gizmos), the new feature cannot be enabled.
- During the transformation, when enabling the feature, if the snap option is turned off in the scene, the snap will be forced on throughout the rest of the transformation (unless interactive mode is canceled).
- During a transformation, if no snap target is set for an element in the scene (Vertex, Grid...), the snap targets to geometry Vertex, Edge, Face, Center of Edge and Perpendicular of Edge will be set automatically.
- Snap cannot be turned off during the snap source editing.
- Constraint or similar modification features will not be available during the snap source editing.
- Text input will not be available during the snap source editing.
- When adding multiple snap points (A) the new prone snap source point will be indicated with an "X" drawing.

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.

Error introduced in rB69d6222481b4 and partially fixed in rB24310441ddc8.

Drop-boxes should act on the context determined through the exact cursor
location. There should be no need to override that, basically by the
nature of how drop-boxes work.
So Campbell and I agreed on removing this.
If we wanted to support it, we'd have to restore the operator context
when drawing drop-boxes, see
https://developer.blender.org/T92501#1247581.

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).

Snapping to an axis aligned view with a 45 degree rotation would
set the view orthographic without setting it back to perspective
when orbiting the view as you would expect with auto-perspective.
Now orthographic is only set for views with rotation of 0, 90, 180, -90.
Notes:
- Partially reverts logic from cebd025e02f1147c48cd658816ad835f94128a4a
at the time RegionView3D.view_axis_roll had not been added,
so only setting the orthographic with one particular rotation
was a bigger limitation than it is now.
- Auto-perspective could be supported when snapping the viewport to
diagonal angles, however that's a larger project.
