Description

Implementations may be able to support an extended address space for sparse memory resources, but only for a certain set of usages.

This extension adds a query for the extended limit, and the supported usages that are allowed for that limit. This limit is an increase to VkPhysicalDeviceLimits::sparseAddressSpaceSize when the VkImage or VkBuffer uses only usages that are supported.
