OpenEXR has some dependecies that other other modules in Blender
requires. When disabling OpenEXR these dependecies could not match
and building blender would fail.
This PR disables the next options when `WITH_IMAGE_OPENEXR=Off`
- `WITH_OPENVDB`
- `WITH_ALEMBIC`
- `WITH_VULKAN_BACKEND`
- `WITH_CYCLES_OSL`
Additionally windows stores the IMath libraries in `IMATH_LIBRARIES`
Linux and Mac stored the IMath libraries in `IMATH_LIBRARY`. This
change will also adds `IMATH_LIBRARIES` variable to all platforms.

Splitting workload dependency chains such that they
only exist within the context of a single frame.
Dependencies are required to ensure sequential
command buffer submissions execute in order,
but the additional dependencies between frames
could incur GPU timeouts, if a signal was delayed.
This could be triggered by both CPU/GPU cycles
texture updates and Viewport Compositor operations.

Reduce register spill to global memory in raytrace_resolve
function. Results in a 20% uplift for this particular shader on
Apple Silicon GPUs. Contributing to 3-5% uplift for scenes
which have SSR enabled. This is achieved via reducing
memory pressure using a packed data type for the sampling
kernel.

Very sadge to see this kind of mistakes still exist in 2023 code...
While in theory this commit could be backported to (LTS) releases, would
rather only do it if/when proven it actually fixes user-facing issues.
Fixing such issues so deep in ID management code can have completely
unexpected side effects.
The framebuffer default size was only set during the first bind. This
is because the `dirty_attachments_ tag` wasn't set and thus the
framebuffer size was never passed down to the GL.
Split to `default_size_set()` to not affect other code paths that use
`size_set()`.
Adds the ability to pack UVs back into the original bounding box.
Choose UV Editor > Menu > UV > Pack Islands
Then change "Pack To" to "Original bounding box"
Face Nearest only works with individual projection, so always set the
`SCE_SNAP_PROJECT` flag in this case.
Also gray out the `Project Individual Elements` option in the UI if
`Face Nearest` is enabled.
And change the description to indicate that `Project Individual Elements`
is always enabled with the `Face Nearest` option.
(I feel a better design for this option needs to be considered).
Avoid introducing another `::modifiers` namespace for now, since it's
not clear if we'll want that long term. This just avoids a bunch of
boilerplate and makes things easier to read.
Use the node group and the properties as arguments instead of
the modifier. This may help to allow reusing the functions outside
of the modifier execution context.
This adds the select more/less operators to the weight paint mode face selection.
Just like in edit mode, press `CTRL`+`Numpad Plus/Minus` to use them.
They have also been added to the `Select` menu.

When retrieving the evaluated mesh to paint on, it can be reevalauted,
where a smaller set of attributes are requested than for regular
evaluated meshes. That reevaluation should be completely removed
(see #106186), but a simple fix in the meantime is to manually
request that data.
When normalization is enabled in the Graph Editor,
the area outside the -1/1 range on the y axis isn't meaningful.
To visually represent that this patch greys out that area
just as it does with anything outside the current frame range.

fast_float.h currently is only used by OBJ, STL and PLY I/O importers.
Update it to the latest release from upstream (from 3.4.0 2020 Nov to
4.0.0 2023 Mar).
No behavior changes, but they have optimized the performance a bit.
Importing a 6-level subdivided Suzanne OBJ file (330MB) goes from 3.5sec
down to 3.2sec on Win10, Ryzen 5950X, VS2022 build.
Previously, fractional scaling was detected but set an integer buffer
scale which the compositor would down-scale causing blurry output.
Now the fractional scaling interface is used when available to set the
DPI and set the internal buffers size & viewport transformation to
ensure 1:1 pixels from Blender to the Wayland output.
Tested to work with multiple monitors with mixed
fractional/non-fractional scale.
Note that this change causes a regression for when fractional scaling
is set on a compositor without support for fractional-scale-v1.
Supporting fractional scaling in both cases is possible but overly
complicated. This case already wasn't working so well - with blurry
output due to image scaling, now the DPI wont be accurate in this case
although Blender is still usable.
It's a bit easier to follow this way, and we can make better use of
const. It's also more reusable in case we have to use it elsewhere
too (for node group operators?).
Use checks for certain node types with better algorithmic complexity.
They should perform better in some edge case with a lot of nodes or
node group nesting. They're now a bit more similar to each other too.
This is the only package that warns about this type of thing, and gets in the
way of actual warnigns on build logs. This requires CMake 3.19+ to take effect,
older versions still show the warnings.
Ensure compression is enabled by using shader_read
flag only. Also ensure that MTLTexture contents
remain in optimal layout for reading after any
data modifications.

The command buffer fails to execute, the cause is unknown. It does not
appear to be related to the binary archive cache as disabling that does
not prevent the issue.

The issue was caused by uninitialized offset used for the scale
variable.
Follow the rest of the usages of the operation which initialize
it explicitly. This makes it very safe and easy fix to backport
to any LTS or corrective release.
Ideally should probably initialize all members in the class
itself, to avoid such situations in the future.

The cycling method for the viewer connection starts searching from the next socket
after the last current connection. If a geometry socket is is the last connected
output this caused the method to jump to the next socket after the geometry,
potentially skipping over valid data sockets that are not viewed yet.
The solution is to ignore the geometry sockets in the cycling entirely and only
consider data sockets (i.e. non-geometry sockets).

This tool now only supports installing packages, it won't build any
dependency anymore. This implies that on most distributions, it wont
make a complete Blender build possible, some features will likely be
misisng.
By default, it only install basic dev environment to enable building
Blender with the precompiled libraries (which is the recommended way).
Passing the `--all` option will make it try to install all known
dependencies from distro packages. This is a development option,
regular Blender build should be done with the precompiled libraries.
Tested on Debian Testing, Arch, Fedora and Suse Tumbleweed.
With the new design, it should be fairly trivial to add more
distributions if desired, and maintenance should also be way simpler.
NOTE: side effect is that a working python3 interpreter is expected on
system running this script. In practice this should not be an issue,
since Python3 is installed by default in almost all regular desktop
linux installations.
The insert key operator allowed to insert a keyframe on all selected FCurves
and on the Active FCurve at cursor value.
But it didn't allow to insert a keyframe only on the active FCurve.
This patch adds that. It is available in the redo panel and under Key->Insert Keyframes (which can also be called with the I hotkey)

This change aimed to solve the following issues:
- Possible threading issue of two tests writing to the same
file, depending on how the ctest is invoked
- Test using the release directory, and potentially leaving
temp file behind on test failure, breaking code sign on
macOS.

Found together with a fix for #106043.
Edge panning (in Node Editors, Outliner and VSE) does unnecessary
updates when the view has not changed at all. This includes adding
`MOUSEMOVE` events (even if you dont move the mouse at all).
Adding `MOUSEMOVE` events results in the transform system constantly running (even if you dont move the mouse) which we certainly want to avoid.
Rectify this by only calling these updates when the view changes.
Pull Request: https://projects.blender.org/blender/blender/pulls/106301
The fix for #105363 (6d3ce8273a) made the transform system respect
(Frame) nodes `offsetx`/`offsety`.
Now Node Editors run the transform system even if the mouse is still (due to edge panning -- unnecessarily, see PR #106301 for fixing this). And due to the way `frame_node_prepare_for_draw` recalculates these offsets (based on
on updated positions and `node.runtime->totr` [which in turn gets rounded in `node_update_basis` -- so subpixel precision is lost there, see [1]]), this can lead to slight imprecisions/noise/jitter during transform (if we use float offsets, see the PR for more info).
So to counter this, use rounded offsets now [which will keep the whole circle stable].
NOTE: PR #106301 would fix this already for having the cursor still, but this patch still improves slight jitter when moving, so will commit separately.
