The library makes calls to `vkAllocateMemory()` and `vkFreeMemory()` internally.
You can setup callbacks to be informed about these calls, e.g. for the purpose

VmaAllocatorCreateInfo::pDeviceMemoryCallbacks.
\subsection heap_memory_limit Device heap memory limit
If you want to test how your program behaves with limited amount of Vulkan device
memory available (without switching your graphics card to one that really has
smaller VRAM), you can use a feature of this library intended for this purpose.
To do it, fill optional member VmaAllocatorCreateInfo::pHeapSizeLimit.

If not NULL, it must be a pointer to an array of

Any of the elements may be equal to `VK_WHOLE_SIZE`, which means no limit on that
heap. This is also the default in case of `pHeapSizeLimit` = NULL.
If there is a limit defined for a heap:
- If user tries to allocate more memory from that heap using this allocator,
the allocation fails with `VK_ERROR_OUT_OF_DEVICE_MEMORY`.
- If the limit is smaller than heap size reported in `VkMemoryHeap::size`, the
value of this limit will be reported instead when using vmaGetMemoryProperties().
