New versions of this library support creating dedicated allocations in custom pools.
It is supported only when VmaPoolCreateInfo::blockSize = 0.
To use this feature, set VmaAllocationCreateInfo::pool to the pointer to your custom pool and
VmaAllocationCreateInfo::flags to #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT.
\section custom_memory_pools_MemTypeIndex Choosing memory type index
When creating a pool, you must explicitly specify memory type index.
