rBa8f7d41d3898 added a "duplicate" check for being in curves sculptmode
unnecessarily afaict (`in_sculpt_curve_mode` in addition to the
previously existing `in_curves_sculpt_mode`).
Over time, the later evolved to also take into account the output of a
viewer node, see rBc55d38f00b8c (the previously existing
`in_curves_sculpt_mode` did not receive this).
This all results in the fact that selection is not drawn with a viewer
node (can be useful though, and there are separate opacity controls for
both selection and the viewer attribute, so these can be used/blended to
everyones liking).
So now deduplicate the check.

A Loop to poly map was passed as an optional output to the loop normal
calculation. That meant it was often recalculated more than necessary.
Instead, treat it as an optional argument. This also helps relieve
unnecessary responsibilities from the already-complicated loop normal
calculation code.
The viewport cleans up old subdivision buffers right after drawing.
During rendering this was not done and when rendering many frames
this lead to memory issues.
This patch will also clear up the GPU Subdivision buffers after any
offscreen render or final render. There is already a mutex so this
is safe to be done from a non main thread.
Thanks to @kevindietrich to finding the root cause.
Properly initialize clump curve mapping tables for duplis and other cases
where this was missed by making a generic init/free function instead of
duplicating the same logic in multiple places. Also fold lattice deform
init into this.
The new Xcode 14.1 brings the new Apple Clang compiler which
considers sprintf unsafe and geenrates deprecation warnings
suggesting to sue snprintf instead. This only happens for C++
code by default, and C code can still use sprintf without any
warning.
This changes does the following:
- Whenever is trivial replace sprintf() with BLI_snprintf.
- For all other cases use the newly introduced BLI_sprintf
which is a wrapper around sprintf() but without warning.
There is a discouragement note in the BLI_sprintf comment to
suggest use of BLI_snprintf when the size is known.

Use the node topology cache and avoid modifying the node tree
in a non-threadsafe way to improve the predictability of using
the helper function. Replaces the implementation from
e0d4047136.
Currently there are both "EDGERENDER" and "EDGEDRAW" flags, which are
almost always used together. Both are runtime data and not exposed to
RNA, used to skip drawing some edges after the subdivision surface
modifier. The render flag is a relic of the Blender internal renderer.
This commit removes the render flag and replaces its uses with the
draw flag.
This patch introduces the concept of a Cached Resource that can be
cached across compositor evaluations as well as used by multiple
operations in the same evaluation. Additionally, this patch implements a
new structure for the realtime compositor, the Static Cache Manager,
that manages all the cached resources and deletes them when they are no
longer needed.
This improves responsiveness while adjusting compositor node trees and
also conserves memory usage.

This moves the implementation from the View to the draw manager itself.
However, this is not its final place and should be moved to the shader
create info at some point in the future.
For now it is not possible because of possible interaction with the
old draw manager codebase.
The goal is to improve clarity and readability, without
introducing big design changes.
Follows the recent obmat to object_to_world refactor: the
similar naming is used, and it is a run-time only rename,
meaning, there is no affect on .blend files.
This patch does not touch the redundant inversions. Those
can be removed in almost (if not all) cases, but it would
be the best to do it as a separate change.

Motivation is to disambiguate on the naming level what the matrix
actually means. It is very easy to understand the meaning backwards,
especially since in Python the name goes the opposite way (it is
called `world_matrix` in the Python API).
It is important to disambiguate the naming without making developers
to look into the comment in the header file (which is also not super
clear either). Additionally, more clear naming facilitates the unit
verification (or, in this case, space validation) when reading an
expression.
This patch calls the matrix `object_to_world` which makes it clear
from the local code what is it exactly going on. This is only done
on DNA level, and a lot of local variables still follow the old
naming.
A DNA rename is setup in a way that there is no change on the file
level, so there should be no regressions at all.
The possibility is to add `_matrix` or `_mat` suffix to the name
to make it explicit that it is a matrix. Although, not sure if it
really helps the readability, or is it something redundant.

This was because `stroke_id` was not using `vertex_start`.
But since `vertex_start` is not 1 based like it used to be, we need to add
1 to it to avoid a fragment depth of `0.0` which would be equal to the
background and not render.
This allows using drawcalls with non default vertex range.
These calls will be culled like any other instance by the GPU culling
pipeline. But they will not be batched together since the vertex range
is part of the group.
* External engines do not use the PBVH and need slower depsgraph updates.
* Final depsgraph tag after stroke finishes was missing for sculpt color
painting, caused missing updates for other viewports as well as any
modifiers or nodes on other objects using the colors.
This change the attribute binding scheme to something similar to the
curves objects. Attributes are now buffer textures sampled per points.
The actual geometry is now rendered using an index buffer that avoid too
many vertex shader invocation.
Drawcall is wrapped in a DRW function to reduce complexity of future
changes.
In T93382, the problem was that the Blender-side rendering code was
still generating the subsurface passes because the old render pass
flags were set, even though Cycles doesn't generate them anymore.
After a closer look, it turns out that the entire hardcoded pass
creation code can be removed. We already have an Engine API function
to query the list of render passes from the engine, so we might as
well just call that and create the returned passes.
Turns out that Eevee already did this anyways. On the Cycles side, it
allows to deduplicate a lot of `BlenderSync::sync_render_passes`.
Before, passes were defined in engine.py and in sync.cpp. Now, all
passes that engine.py returns are created automatically, so sync.cpp
only needs to handle a few special cases.
I'm not really concerned about affecting external renderer addons,
since they already needed to handle the old "builtin passes" in
their Engine API implementation anyways to make them show up in the
compositor. So, unless they missed that for like 10 releases, they
should not notice any difference.
