NullStRec structure
#include <TextEdit.h>
typedef struct NullStRec { Size Offset Description
long teReserved; 4 0 Height of this line, in points (bit 15
masked)
StScrpHandle nullScrap; 4 4 Ascent of tallest character/face in this
line
typedef NullStRec *NullStPtr;
typedef NullStRec **NullStHandle;

Notes: The NullStRec structure is maintained to describe the default format for
text which is added when the selection range is an insertion point. It is not
used directly in any TextEdit function.
The nullScrap field leads to an StScrpRec which eventually leads to a
ScrpSTElement defining the "null style" style.
