VulkanMemoryAllocator/docs/html/struct_vma_defragmentation_info2.html
Adam Sawicki 72983b0aa1 Clarified documentation in few places to mention textures need to use LINEAR layout when accessed from the host 
Rebuilt HTML documentation. Used new Doxygen 1.8.18.

<p>Either null or pointer to array of pools to be defragmented. </p>
<p>All the allocations in the specified pools can be moved during defragmentation and there is no way to check if they were really moved as in <code>pAllocationsChanged</code>, so you must query all the allocations in all these pools for new <code>VkDeviceMemory</code> and offset using <a class="el" href="vk__mem__alloc_8h.html#a86dd08aba8633bfa4ad0df2e76481d8b" title="Returns current information about specified allocation and atomically marks it as used in current fra...">vmaGetAllocationInfo()</a> if you might need to recreate buffers and images bound to them.</p>
<p>The array should have <code>poolCount</code> elements. The array should not contain nulls. Elements in the array should be unique - same pool cannot occur twice.</p>
<p>Using this array is equivalent to specifying all allocations from the pools in <code>pAllocations</code>. It might be more efficient. </p>
