/**
* Describes parameter of created {@code VmaPool}.
*
* Member documentation
*
*
* - {@code memoryTypeIndex} – Vulkan memory type index to allocate this pool from
* - {@code flags} – Use combination of {@code VmaPoolCreateFlagBits}. One or more of:
{@link Vma#VMA_POOL_CREATE_IGNORE_BUFFER_IMAGE_GRANULARITY_BIT POOL_CREATE_IGNORE_BUFFER_IMAGE_GRANULARITY_BIT} {@link Vma#VMA_POOL_CREATE_LINEAR_ALGORITHM_BIT POOL_CREATE_LINEAR_ALGORITHM_BIT} {@link Vma#VMA_POOL_CREATE_BUDDY_ALGORITHM_BIT POOL_CREATE_BUDDY_ALGORITHM_BIT} {@link Vma#VMA_POOL_CREATE_ALGORITHM_MASK POOL_CREATE_ALGORITHM_MASK}
* - {@code blockSize} –
* size of a single {@code VkDeviceMemory} block to be allocated as part of this pool, in bytes. Optional.
*
*
Specify nonzero to set explicit, constant size of memory blocks used by this pool. Leave 0 to use default and let the library manage block sizes
* automatically. Sizes of particular blocks may vary.
* - {@code minBlockCount} –
* minimum number of blocks to be always allocated in this pool, even if they stay empty.
*
*
Set to 0 to have no preallocated blocks and allow the pool be completely empty.
* - {@code maxBlockCount} –
* maximum number of blocks that can be allocated in this pool. Optional.
*
*
Set to 0 to use default, which is {@code SIZE_MAX}, which means no limit. Set to same value as {@link VmaPoolCreateInfo}{@code ::minBlockCount} to have fixed
* amount of memory allocated throughout whole lifetime of this pool.
* - {@code frameInUseCount} –
* maximum number of additional frames that are in use at the same time as current frame.
*
*
This value is used only when you make allocations with {@link Vma#VMA_ALLOCATION_CREATE_CAN_BECOME_LOST_BIT ALLOCATION_CREATE_CAN_BECOME_LOST_BIT} flag. Such allocation cannot become lost if
* {@code allocation.lastUseFrameIndex >= allocator.currentFrameIndex - frameInUseCount}.
*
* For example, if you double-buffer your command buffers, so resources used for rendering in previous frame may still be in use by the GPU at the moment
* you allocate resources needed for the current frame, set this value to 1.
*
* If you want to allow any allocations other than used in the current frame to become lost, set this value to 0.
*
