4. Verify images have CmdPipelineBarrier layouts matching new layout parameters to Cmd*Image* functions
6. For specific object instances that are allowed to be NULL, update object validation to verify that such objects are either NULL or valid
7. Verify cube array VkImageView objects use subresourceRange.arraySize (or effective arraySize when VK_REMAINING_ARRAY_SLICES is specified) that is a multiple of 6.
+ 8. Make object maps specific to instance and device. Objects may only be used with matching instance or device.
+ 9. Use reference counting for non-dispatchable objects. Multiple object creation calls may return identical handles.
## Threading
1. For Upcoming Dynamic State overhaul (if approved): If dynamic state value that is consumed is never set prior to consumption, flag an error
2. For Upcoming Dynamic State overhaul (if approved): If dynamic state that was bound as "static" in current PSO is attempted to be set with vkCmdSet* flag an error
3. Need a WSI validation layer(s) to validate correct usage of WSI API. One issue that has already come up is correct UsageFlags for WSI SwapChains and SurfaceProperties. Tons of other stuff including semaphore and synchronization validation.
