34: * A window an array of __LINE structures pointed to by the 'lines' pointer.
35: * A line is an array of __LDATA structures pointed to by the 'line' pointer.
36: *
37: * IMPORTANT: the __LDATA structure must NOT induce any padding, so if new
38: * fields are added -- padding fields with *constant values* should ensure
39: * that the compiler will not generate any padding when storing an array of
40: * __LDATA structures. This is to enable consistent use of memcmp, and memcpy
41: * for comparing and copying arrays.
