 /* Allocate memory.  For reasonable files, size should never exceed
  * 64K.  However, zlib may allocate more then 64K if you don't tell
  * it not to.  See zconf.h and png.h for more information.  zlib does
  * need to allocate exactly 64K, so whatever you call here must
  * have the ability to do that.
