VkBuffer
objects created with the
VK_BUFFER_CREATE_SPARSE_RESIDENCY_BIT
bit allow the buffer to be made
only partially resident. Partially resident VkBuffer
objects are
allocated and bound identically to VkBuffer
objects using only the
VK_BUFFER_CREATE_SPARSE_BINDING_BIT
feature. The only difference is
the ability for some regions of the buffer to be unbound during device use.
