This command can reduce the time it takes the CPU to access a texture. Apps typically run the command for:
Textures the CPU accesses for an extended period of time
Textures with a storageMode property that’s MTLStorageMode.shared or MTLStorageMode.managed
When a blit pass runs this command, the GPU only applies lossless changes to the texture’s underlying data.
