the commit causes test failures in older releases, we may not be able to fix them without introducing regressions

9faa5601 AcquireDrawInfo() instead of magick_malloc()-ing some memory introduced memory leak in 2.16.0-6 by calling AcquireDrawInfo without removing the GetDrawInfo call in DrawOptions_initialize. AcquireDrawInfo internally calls GetDrawInfo. The double call to GetDrawInfo causes this leak. Bionic and Xenial are therefore unaffected.
