Detailed Description

template<typename TValue>
struct itk::VariableLengthVector< TValue >::DontShrinkToFit

VariableLengthVector Allocation Policy: reallocate memory only when size increases. This policy, when used from VariableLengthVector::SetSize(), will reallocate the internal buffer only if the new size requested for the VariableLengthVector increases.

whether newSize is bigger than oldSize
Unlike classes like std::vector<>, VariableLengthVector has no capacity concept: the size of the VariableLengthVector is its capacity. However, this will help a class without capacity to emulate one. The consequence is that reallocations will occur with scenarios such as the following:
v.SetSize(12); // no reallocation
v.SetSize(42); // pointless reallocation (given this policy)
