Release notes:
vklExamples improvements: asynchronous rendering, multiple viewports, docking, and more
Fixed bug in openvkl_utility_vdb which could lead to crashes when creating VDB volumes with temporally constant tiles
Superbuild updates to latest versions of dependencies
Minimum rkcommon version is now 1.8.0

Add branch name explicitly to SRC_URI where it's not defined and switch
to using https protocol for Github projects.
The change was made using convert_srcuri script for OE-Core.

- Fixed issue in `structuredRegular` and `vdb` interval iterators that could
lead to erroneous initial intervals for certain ray inputs
- Fixed handling of `intervalResolutionHint` interval iterator context
parameter for `amr`, `particle`, and `unstructured` volumes with small
numbers of cells / primitives

Release notes:
https://github.com/openvkl/openvkl/blob/master/CHANGELOG.md
Highlights:
The version 1.0 release marks long term API stability (until v2.0)
Open VKL can now be built for ARM CPUs that support Neon
Iterator API updates:
Introducing interval and hit iterator contexts, which hold iterator-specific configuration (eliminates value selector objects)
Interval and hit iteration is now supported on any volume attribute
Interval iterators now include a time parameter
Interval iterators now support the intervalResolutionHint parameter, replacing maxIteratorDepth and elementaryCellIteration
Supporting configurable background values; default is now VKL_BACKGROUND_UNDEFINED (NaN) for all volume types
vklGetValueRange() now supports all volume attributes
Added ISPC-side API bindings for vklGetNumAttributes() and vklGetValueRange()
Structured regular volumes:
Added support for tricubic filtering
More accurate gradient computations respecting filter mode
Hit iteration robustness improvements
VDB volumes:
Interval and hit iteration robustness improvements
Corrected interval iterator nominalDeltaT computation for non-normalized ray directions and non-uniform object-space grid spacings
Fixed bug which could cause incorrect value range computations for temporally varying volumes
vklExamples additions demonstrating:
Multi-attribute interval / hit iteration
Configurable background values
Temporally varying volumes
Superbuild updates to latest versions of dependencies
Now requiring minimum versions:
Embree 3.13.1
rkcommon 1.7.0
ISPC 1.16.0
License-Update: Copyright years updated

Use the convert-overrides.py to convert to new syntax and manually
fix some additional changes.

Intel(R) Open Volume Kernel Library (Intel(R) Open VKL) is a collection of
high-performance volume computation kernels, developed at Intel. The
target users of Open VKL are graphics application engineers who want to
improve the performance of their volume rendering applications by
leveraging Open VKL’s performance-optimized kernels, which include
volume traversal and sampling functionality for a variety of volumetric
data formats. The kernels are optimized for the latest Intel(R) processors
with support for SSE, AVX, AVX2, and AVX-512 instructions.
Open VKL provides a C API, and also supports applications written with
the Intel(R) Implicit SPMD Program Compiler (Intel(R) ISPC) by also
providing an ISPC interface to the core volume algorithms. This makes it
possible to write a renderer in ISPC that automatically vectorizes and
leverages SSE, AVX, AVX2, and AVX-512 instructions. ISPC also supports
runtime code selection, thus ISPC will select the best code path for
your application.
