From: Alejandro Piñeiro <[email protected]>
It uses VK_KHR_get_physical_device_properties2 functionality to expose
if the extension is supported or not.
v2: update due rebase against master (Alejandro)
v3: (Jason Ekstrand)
- Move this patch up in VK_KHR_16bit_storage series enabling only
storageBuffer16BitAccess and uniformAndStorageBuffer16BitAccess.
- Only expose VK_KHR_16bit_storage on Gen8+
