This feature has been desired for some time:
- https://rightclickselect.com/p/ui/Tqbbbc/allow-navigating-while-transforming (See comments);
- D1583;
- T37427;
In short, blocking navigation during transform limits the user to move the object only to visible areas within the screen and hinders the allocation of objects within closed meshes.
The node editor is also impaired because some nodes are far between them and the connectors are too small.
The only disadvantage of this patch (as I see it) is the conflict with the existing key map:
MIDDLEMOUSE:
- enable axis constrain in 3D view;
WHEELDOWNMOUSE, WHEELUPMOUSE, PAGEUPKEY, PAGEDOWNKEY:
- change the threshold of the proportional edit;
So the patch solution was to change these keymaps:
- MIDDLEMOUSE to Alt+MIDDLEMOUSE;
- WHEELDOWNMOUSE, WHEELUPMOUSE, PAGEUPKEY, PAGEDOWNKEY to Alt+(corresponding key);
When you use this new keymap for the first time in the proportional edit, it may seem strange due to the custom of using it (both in View2D and View3D).
But quickly the user gets used to it.
Alternatively we can add an option to the user preferences ([] Allow navigating while transforming). (I'm not much fan of this option).
The patch was done on branch2.8. But maybe it's a good idea to apply it to 2.79

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.

Add the "Convert Old Pose Library" operator to the old pose library (in
the Armature properties editor). This makes it more discoverable; before
it only was available in the Action editor.
When filtering the asset browser, also include results that have partial
tag matches. So searching for "xite" will include results tagged with
"excited".
This brings the tag filtering in line with other search boxes in
Blender. Later we might want to provide users with more options for
prefix-only ("excite" would match "excited", but "xited" would not) or
only exact matches.
The Cycles accurate mode was removed, but the Eevee option for this has
a different meaning and should not have been removed. The Eevee accurate
makes cryptomatte accumulate for every sample, which Cycles has always
done regardless of any option.
MSL requires that constant address space literals be declared at program
scope. This patch moves the `blackbody_table_r/g/b` and `cie_colour_match`
constants into separate files so they can be declared at the appropriate scope.

This patch contains many small leftover fixes and additions that are
required for Metal-enablement:
- Address space fixes and a few other small compile fixes
- Addition of missing functionality to the Metal adapter headers
- Addition of various scattered `__KERNEL_METAL__` blocks (e.g. for
atomic support & maths functions)

Previously the check was done based on dimension of image and if any
of dimensions were larger than tile size tiling was used.
This change makes it so that if image does not exceed number of pixels
in the tile no tile will be used. Allows to render widescreen images
without tiling.

The calculation based on preserving device occupancy was conflicting
with the fact that time limit needs to render less samples at the last
round of render work.
For example, rendering BMW27 for 30sec on i9-11900k was actually
rendering for almost a minute. Now the render time limit is respected
much more close.

Build HIP kernels with NanoVDB, and patch NanoVDB to work with HIP.
This is a header only library so no rebuild is needed. The changes are being
submitted upstream to openvdb, so this patch should be temporary.
Thanks Thomas for help testing this.
For data-blocks from the current file, the image-buffer for dragging
wasn't set at all. This wasn't intentional, dragging things in the Asset
Browser should just always show the preview.
stack_assign_if was used in the middle of creating the shader value blocks.
Which caused stack variables to be inserted in the middle of the shader value data.
This resulted in the shader node data no being in sequential order. This was also
the case for the wave texture wave node.

Some when adding multiple movies at once and only some of them have
audio track, this causes crash on NULL dereference. Issue was introduced
in bdbc7e12a0 to align sound and video properly.
Check if sound is present in movie file. If it's not, don't try to align
sound with video.
This patch adds a CMake option "WITH_CYCLES_DEBUG" which builds cycles with
a feature that allows debugging/selecting the direct-light sampling strategy.
The same option may later be used to add other debugging features that could
affect performance in release builds.
The three options are:
* Forward path tracing (e.g., via BSDF or phase function)
* Next-event estimation
* Multiple importance sampling combination of the previous two methods
Such a feature is useful for debugging light different sampling, evaluation,
and pdf methods (e.g., for light sources and BSDFs).
