* 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.
