+ * For color images that have an auxiliary surface, request allocation for an
+ * additional buffer that mainly stores fast-clear values. Use of this buffer
+ * allows us to access the image's subresources while being aware of their
+ * fast-clear values in non-trivial cases (e.g., outside of a render pass in
+ * which a fast clear has occurred).
+ *
+ * For the purpose of discoverability, the algorithm used to manage this buffer
+ * is described here. A clear value in this buffer is updated when a fast clear
+ * is performed on a subresource. One of two synchronization operations is
+ * performed in order for a following memory access to use the fast-clear
+ * value:
+ *    a. Copy the value from the buffer to the surface state object used for
+ *       reading. This is done implicitly when the value is the clear value
+ *       predetermined to be the default in other surface state objects. This
+ *       is currently only done explicitly for the operation below.
+ *    b. Do (a) and use the surface state object to resolve the subresource.
+ *       This is only done during layout transitions for decent performance.
+ *
+ * With the above scheme, we can fast-clear whenever the hardware allows except
+ * for two cases in which synchronization becomes impossible or undesirable:
+ *    * The subresource is in the GENERAL layout and is cleared to a value
+ *      other than the special default value.
+ *
+ *      Performing a synchronization operation in order to read from the
+ *      subresource is undesirable in this case. Firstly, b) is not an option
+ *      because a layout transition isn't required between a write and read of
+ *      an image in the GENERAL layout. Secondly, it's undesirable to do a)
+ *      explicitly because it would require large infrastructural changes. The
+ *      Vulkan API supports us in deciding not to optimize this layout by
+ *      stating that using this layout may cause suboptimal performance. NOTE:
+ *      the auxiliary buffer must always be enabled to support a) implicitly.
+ *
+ *
+ *    * For the given miplevel, only some of the layers are cleared at once.
+ *
+ *      If the user clears each layer to a different value, then tries to
+ *      render to multiple layers at once, we have no ability to perform a
+ *      synchronization operation in between. a) is not helpful because the
+ *      object can only hold one clear value. b) is not an option because a
+ *      layout transition isn't required in this case.
