Error when using discontinuous descriptor sets

[jaebaek]

I found that VkRunner has a bug when there are discontinuous descriptor sets.

This is a script to reproduce the bug.

It works fine if descriptor sets are consecutive numbers from 0 to some positive integer N.
However, it does not work if descriptor sets are discontinuous e.g., 1, 3, 5.

Thanks for reporting the issue. I’ve made a pull request for it in #45.
