The isconnected() returns 2 when used on an output that is connected to another downstream shader node -- this can be used to limit computation to only the outputs used. However, that misses the important case of where the renderer has declared a shader node output as a renderer output, which happens often when using OSL purely for pattern generation purposes. This change makes that case also return 2.
Tests
The isconnected test has been updated to include testing this functionality.
[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.
