## Detailed Description

More detailed statistics than VmaStatistics.

These are slower to calculate. Use for debugging purposes. See functions: vmaCalculateStatistics(), vmaCalculatePoolStatistics().

Previous version of the statistics API provided averages, but they have been removed because they can be easily calculated as:

VkDeviceSize allocationSizeAvg = detailedStats.statistics.allocationBytes / detailedStats.statistics.allocationCount;
VkDeviceSize unusedBytes = detailedStats.statistics.blockBytes - detailedStats.statistics.allocationBytes;
VkDeviceSize unusedRangeSizeAvg = unusedBytes / detailedStats.unusedRangeCount;
