/*
* To transition an image to a new layout, an image barrier is used. Before we see how that is done, let's see
* what it even means.
*
* In Vulkan, there are barriers on different kinds of resources (images, buffers and memory) and other means
* to specify execution dependency. In each case, you want to make sure some actions A are all executed before
* some actions B. In the specific case of barriers, A could be actions that do something to the resource and
* B could be actions that need the result of those actions.
*
* In our specific case, we want to change the layout of a swapchain image. For the transition from present
* src, we want to make sure that all writes to the image are done after the transition is done. For the
* transition to present src, we want to make sure that all writes to the image are done before the transition
* is done. Note: if we had a graphics pipeline, we would be talking about "color attachment writes" instead
* of just "writes". Keep that in mind.
*
* Using a VkImageMemoryBarrier, we are not only specifying how the image layout should change (if changed at
* all), but also defining the actions A and B where an execution dependency would be created. In the first
* barrier (transition from present src), all reads of the image (for previous presentation) must happen before
* the barrier (A is the set of READ operations), and all writes must be done after the barrier (B is the set
* of WRITE operations). The situation is reversed with the second barrier (transition to present src).
*
* In Vulkan, actions A are referred to as `src` and actions B are referred to as `dst`.
*
* Using an image barrier, it's also possible to transfer one image from a queue family to another, in which
* case A is the set of actions accessing the image in the first queue family and B is the set of actions
* accessing the image in the second queue family. We are not moving between queue families, so we'll specify
* this intention as well.
*
* In our layout transition, we are transitioning from present src to to_layout and back. However, the first
* time the transition happens, the swapchain image layout is actually UNDEFINED. Either way, since we are not
* interested in what was previously in the image when we are just about to render into it, we can set the
* `oldLayout` (the layout transitioning from) to UNDEFINED. This makes the transition more efficient because
* Vulkan knows it can just throw away the contents of the image. Note: in Tutorial 7, we are transition to
* "general", but if we had a graphics pipeline, we would be transition to the "color attachment optimal"
* layout instead.
*
* Finally, we need to specify which part of the image (subresource) is being transitioned. We want to
* transition COLOR parts of the image (which in this case, all of the image is COLOR), and all mip levels and
* arrays (which are both in this case single).

/*
* The image barrier structure above defines the execution dependency of sets of actions A and B. When
* applying the barrier, we also need to specify which pipeline stages these sets of actions are taken from.
*
* In our barrier, first we want to make sure all READs from the image (by the previous presentation) is done
* before the barrier. These reads are not part of our rendering. In fact, they are really done before the
* graphics pipeline even begins. So the pipeline stage we specify for `src` would be the top of the pipeline,
* which means before the pipeline begins. Second, we want to make sure all writes to the image (for
* rendering) is done after the barrier. The writes to the image are likely to happen at later stages of the
* graphics pipeline, so we can specify those stages as `dst` stages of the barrier. We have already specified
* that the barrier works on WRITEs, so we can also be a bit lazy and say that the `dst` stage is all graphics
* pipeline stages.
*
* Let's rephrase the above to make sure it's clear. The vkCmdPipelineBarrier takes a src and dst stage mask.
* The arguments are called srcStageMask and dstStageMask. They can contain more than one pipeline stage.
* Take the combinations (srcAccessMask, srcStageMask) and (dstAccessMask, dstStageMask). Say we make a
* barrier from (A, Sa) to (B, Sb) as src and dst parts of the barrier respectively. The barrier then means
* that all actions A in stages Sa are done before all actions B in stages Sb. So, if Sb is all graphics
* stages, it means that all actions A in stages Sa are done before all actions B anywhere. If Sa is top of
* the pipeline, it means that all actions A before the pipeline are done before all actions B anywhere.
*
* All READs before the pipeline must be done before all WRITEs anywhere.
