-// MemoryActivatedFont encapsulates a font loaded from another process and

-//
-// Responsibilities:
-// * Holder for the CGFontRef & ATSFontRef belonging to the activated font.
-// * Responsible for unloading the font container when done.
-//
-// Memory Management:
-// The class is reference counted, with each instance of FontPlatformData that
-// uses this class holding a reference to it.
-// Entries are kept track of internally in a hash to allow quick lookup
-// of existing instances for reuse:
-// - fontCacheBySrcFontContainerRef() - key is the ATSFontContainerRef
-//   corresponding to the *original in-process NSFont* whose loading was blocked
-//   by the sandbox.
-//   This is needed to allow lookup of a pre-existing MemoryActivatedFont when
-//   creating a new FontPlatformData object.
-//
-// Assumptions:
-// This code assumes that an ATSFontRef is a unique identifier tied to an
-// activated font.  i.e. After we activate a font, its ATSFontRef doesn't
-// change.
-// It also assumes that the ATSFoncontainerRef for two in-memory NSFonts that
-// correspond to the same on-disk font file are always the same and don't change
-// with time.
-//
-// Flushing caches:
-// When the system notifies us of a system font cache flush, all FontDataCache
-// objects are destroyed.  This should in turn dereference all
-// MemoryActivatedFonts and thus unload all in-memory fonts.
