| * We use the bindless descriptor model, which maps fairly closely to how |
| * Vulkan descriptor sets work. The two exceptions are input attachments and |
| * dynamic descriptors, which have to be patched when recording command |
| * buffers. We reserve an extra descriptor set for these. This descriptor set |
| * contains all the input attachments in the pipeline, in order, and then all |
| * the dynamic descriptors. The dynamic descriptors are stored in the CPU-side |
| * datastructure for each tu_descriptor_set, and then combined into one big |
| * descriptor set at CmdBindDescriptors time/draw time. |
