/* Allowing different clear colors requires us to perform a depth resolve at

 * the clear color in the HiZ buffer, fast clears (without a resolve) don't.
 * See the PRMs for examples describing when additional resolves would be
 * necessary. To enable fast clears without requiring extra resolves, we set
 * the clear value to a globally-defined one. We could allow different values
 * if the user doesn't expect coherent data during or after a render passes
 * (VK_ATTACHMENT_STORE_OP_DONT_CARE), but such users (aside from the CTS)
 * don't seem to exist yet. In almost all Vulkan applications tested thus far,
 * 1.0f seems to be the only value used. The only application that doesn't set
 * this value does so through the usage of an seemingly uninitialized clear
