*=============================================================================
*
* cpgsbox() and cpglbox() are C wrappers for PGSBOX and PGLBOX. Refer to the
* prologue of pgsbox.f for an explanation of the argument list and usage
* notes.
*
* The argument lists for cpgsbox()/cpglbox() differ from PGSBOX/PGLBOX in
* the following respects:
*
* idents char[3][80]
* Fixed length character array.
* opt char[2] Fixed length character array.
* nlfunc nlfunc_t typedef for external function defined in cpgsbox.h.
* cache double[][4]
* Array indices reversed.
*
* Note also that the array arguments to cpgsbox()/cpglbox() are all
* 0-relative, while several of those of PGSBOX/PGLBOX are 0-relative (GRID1,
* GRID2, and CACHE) with the remainder 1-relative. In particular, the two-
* dimensional CACHE array has a mixture of 0-, and 1-relative indices, and
* the indices are reversed in C because of the differing C and FORTRAN array
* indexing policy. Moreover, as in PGSBOX/PGLBOX, nc is the upper array
* index, not the array length, so the array should be dimensioned as
* cache[nc+1][4].
