%  Segregate our memory requirements from any program that calls our API.  This
%  should help reduce the risk of others changing our program state or causing
%  memory corruption.
%
%  Our custom memory allocation manager implements a best-fit allocation policy
%  using segregated free lists.  It uses a linear distribution of size classes
%  for lower sizes and a power of two distribution of size classes at higher
%  sizes.  It is based on the paper, "Fast Memory Allocation using Lazy Fits."
%  written by Yoo C. Chung.
%
%  By default, C's standard library is used (e.g. malloc);  use the
%  custom memory allocator by defining MAGICKCORE_ANONYMOUS_MEMORY_SUPPORT
%  to allocate memory with private anonymous mapping rather than from the
%  heap.
