data :: A typeless pointer to any client-specified data. This field is completely ignored by the FreeType library.
finalizer :: A pointer to a `generic finalizer' function, which will be called when the object is destroyed. If this field is set to NULL, no code will be called. typedef struct FT_Generic_ { void* data; FT_Generic_Finalizer finalizer; } FT_Generic;
Client applications often need to associate their own data to a variety of FreeType core objects. For example, a text layout API might want to associate a glyph cache to a given size object. Most FreeType object contains a `generic' field, of type FT_Generic, which usage is left to client applications and font servers. It can be used to store a pointer to client-specific data, as well as the address of a `finalizer' function, which will be called by FreeType when the object is destroyed (for example, the previous client example would put the address of the glyph cache destructor in the `finalizer' field).

FT_MAKE_TAG
This macro converts four letter tags which are used to label TrueType tables into an unsigned long to be used within FreeType. #define FT_MAKE_TAG( _x1, _x2, _x3, _x4 ) ( ( (FT_ULong)_x1 << 24 ) | ( (FT_ULong)_x2 << 16 ) | ( (FT_ULong)_x3 << 8 ) | (FT_ULong)_x4 ) L I S T M A N A G E M E N T
