To avoid too much noise, the help circles are only visible if the
the gap is still open. When the gap is closed, the circles are hidden.
Hiding the circles makes it easier to focus on what is problematic.
instead, to see many circles that are already resolved.
The motivation for this change: while working on an animation recently, I found that there are some gaps that won't close easily via stroke extension or leak size checking. In D14698, I attempted to address this by changing the algorithm of the raster-space flood fill. This patch attempts to address the same issue in vector space by adding two new cases where stroke extensions are added, as suggested by @frogstomp:
# **Points of high curvature:** when the curvature at a point is high enough that it's hard to visually distinguish between it and an endpoint, add a stroke extension out along the normal (pointing in the opposite direction of the stroke's acceleration.) This addresses cases where technically the endpoint points up, but there's a sharp corner right below it that should extend to connect.
# **Stroke endpoints within a radius**: when two endpoints are close together, regardless of the angle they make, connect them if they are within a radius. This addresses cases like where the two endpoints have effectively parallel tangents, so extensions won't close the gap.

Returns a new range, that contains the intersection of the current one
with the given range.
This is helpful to select a portion of a range without having to deal with
all the asserts of other functions. The resulting range being always a
valid subrange, it can be used to iterate or copy a part of a vector.
This reduces logging overhead. The performance difference is only
significant when there are many fast nodes. In my test file with many
math nodes, the performance improved from 720ms to 630ms.
Caused by clamping handle translation to strip bounds in functions
`SEQ_time_*_handle_frame_set()` to prevent strip ending in invalid
state. Issue happens when meta strip is moved so quickly, such that
immediate offset is greater than strip length.
Currently meta strip bounds are updated when any contained strip changes
its position, but this update always preserves meta strip position.
Transforming meta strip is not possible directly and all contained
strips are moved instead. Therefore this is 2-step process and fix needs
to be applied on update function and on translation function.
Inline offset handling without clamping in function
`SEQ_time_update_meta_strip_range()`.
Add new function `seq_time_translate_handles()` to move both handles at
once in `SEQ_transform_translate_sequence()`.
Avoid conversion to `BMesh` for basic topology operations and data access.
Instead use a mesh map to retrieve the faces connected to each edge.
I observed performance improvements of 5x (600ms to 100ms) to 10x
(15s to 1s), with bigger changes for large meshes with more data layers
Switching to `std::queue` over Blender's `GSQueue` gave another
25% improvement.

Caused by ee23f0f3fb, which removed the update tag when entering
sculpt mode, and by b5f7af31d6, which made these layers lazily
created, so they weren't always available at the start of a stroke. Now
update the evaluated mesh/multires CCG as necessary. Some updates
could potentially avoided when switching modes in the future, but for
now do it all the time.
Fixes T101116
Also fixes a crash when painting multires mask for the first time
New unified attribute API for sculpt code.
= Basic Design =
The sculpt attribute API can create temporary or permanent attributes (only supported in `PBVH_FACES` mode). Attributes are created via `BKE_sculpt_attribute_ensure.`
Attributes can be explicit CustomData attributes or simple array-based pseudo-attributes (this is useful for PBVH_GRIDS and PBVH_BMESH).
== `SculptAttributePointers` ==
There is a structure in `SculptSession` for convenience attribute pointers, `ss->attrs`. Standard attributes should assign these; the attribute API will automatically clear them when the associated attributes are released. For example, the automasking code stores its factor attribute layer in `ss->attrs.automasking_factor`.
== Naming ==
Temporary attributes should use the SCULPT_ATTRIBUTE_NAME macro for naming, it takes an entry in `SculptAttributePointers` and builds a layer name.
== `SculptAttribute` ==
Attributes are referenced by a special `SculptAttribute` structure, which holds
all the info needed to look up elements of an attribute at run time.
All of these structures live in a preallocated flat array in `SculptSession`, `ss->temp_attributes`. This is extremely important. Since any change to the `CustomData` layout can in principle invalidate every extant `SculptAttribute`, having them all in one block of memory whose location doesn't change allows us to update them transparently.
This makes for much simpler code and eliminates bugs. To see why this is tricky to get right, imagine we want to create three attributes in PBVH_BMESH mode and we provide our own `SculptAttribute` structs for the API to fill in. Each new layer will invalidate the `CustomData` block offsets in the prior one, leading to memory corruption.

The new evaluator crashes for multi-input sockets coming from undefined
nodes. The multi-input socket lazy node tries to retrieve the default
value since the undefined node never created output values. But there
is no default value stored because the socket is linked.

Smooth flag should come from the evaluated mesh, only selection and hidding

Pre-existing issue revealed by refactor in b247588dc0.
This was essentially a use-after-free issue. When a geometry nodes
group changes it has to be preprocessed again before it can be evaluated.
This part was working, the issue was that parent node groups have to be
preprocessed as well, which was missing. The lazy-function graph cached
on the parent node group was still referencing data that was freed when
the child group changed.
Now the depsgraph makes sure that all relevant geometry node groups are
preprocessed again after a change.
This issue was found by Simon Thommes.
Sun Disc is currently not supported because it'll need special handling - on the one hand, I'm not sure if Eevee would handle a 1e6 coming out of a background shader without issues, and on the other hand it won't actually cast sharp shadows anyways.
I guess we'd want to internally add a sun to the lamps if Sun Disc is enabled, but getting that right is tricky since the user could e.g. swap RGB channels in the node tree and the lamp wouldn't match that.
Anyways, that can be handled later, the sky itself is already a start.

This reverts commit 34051fcc12.
Although for normal use this doesn't make a difference. But when working with
huge scenes and volumetrics + NVIDIA it made a work-around not possible anymore.
For the heist production we added a fix on the render-farm (enable GPU workarounds).
{rB34051fcc12f388375697dcfc6da53e9909058fe1} made another work-around not
accessible anymore and it and was requested to revert this change.

Different areas of the mesh can be "loose parts" visually when separated
by hidden areas. This is consistent with other areas of sculpt mode that
also treat hidden areas differently.
- Add doc-string with example usage shown in the --help message.
- Add help text for command line arguments.
- Only search for the CMakeCache.txt file when the `--build-dir`
is omitted.
- Write fatal errors to the stderr.
We need to use the custom data copy function that skips mesh-only
attributes like the hide status attributes, the generic material index
attribute, etc. Otherwise the BMesh has those attributes which
conflict with their builtin counterparts.
The buildbot will call this script to create a binary .whl file that can be
easily installed through pip.
This wheel will only work with the same Python version used for Blender.
Other minimum system requirements are the same as regular Blender builds.
