The resource subsystem creates buffers, images, buffer views and image views in a single batch operation, using a single memory object to back all the buffers and images. I had been doing this by hand for a while, but got tired of jumping through all those vulkan hoops. While it's still a little tedious to set up the arrays for QFV_CreateResource (and they need to be kept around for QFV_DestroyResource), it really eases calculation of memory object size and sub-resource offsets. And destroying all the objects is just one call to QFV_DestroyResource.
