This requires you to first declare a setting for the dynamic array input that
will be used to size and provide values for any unconnected elements of the
dynamically sized array. After that, individual scalar->arrayelem connections
can be specified from any number of different upstream shading nodes. This
facilitates gathering inputs from across your shading network, for example
several procedurally generated color signals and using them to drive inputs
to shading nodes that are best left dynamically sized, such as the inputs
to spline operations.
Tests
This includes a new test in vararray-scalar-connect to demonstrate and
test the new connection method.
[X] I have updated the documentation, if applicable.
[X] I have ensured that the change is tested somewhere in the testsuite (adding new test cases if necessary).
[X] My code follows the prevailing code style of this project. If I haven't
already run clang-format v17 before submitting, I definitely will look at
the CI test that runs clang-format and fix anything that it highlights as
being nonconforming.
