-The exact maximum sample count can be extracted from `VkPhysicalDeviceProperties` associated with our selected physical device. We're using a depth buffer, so we have to take into account the sample count for both color and depth - the lower number will be the maximum we can support. If the hardware supports only one sample the final image will look unchanged. Add a function that will fetch this information for us:
+By default we'll be using only one sample per pixel which is equivalent to no multisampling, in which case the final image will remain unchanged.
