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