Notes: See Standard Cursors for a graphic depiction of various cursors.
The cursor is defined as the contents of two 16 by 16 rectangles. When
drawn, the mask is XORed at the current location (clearing out anything behind
the bits) and the data is ORed:
This Cursor structure is used in calls to ‹GetCursor and
‹SetCursor. Resources of type 'CURS' contain data in this
format.
The Quickdraw global variable ›arrow defines the standard
left-leaning arrow cursor. Other standard cursors are in
the system resource file.
