tickit_renderbuffer_clip, tickit_renderbuffer_mask - restrict the drawing area of output functions

tickit_renderbuffer_clip()  restricts  the  clipping  rectangle  to the limits given, within the existing
       limits already set. This function cannot make the clipping region larger than it already was.

       tickit_renderbuffer_mask() applies a rectangular mask within the clipping region, masking off extra cells
       that can no longer be modified by the output functions. Unlike tickit_renderbuffer_clip()  these  regions
       can  be  arbitrarily positioned and discontinuous; each new call adds another masking region, rather than
       affecting the existing ones.

       To undo the effects of any of these functions, they should be  used  within  nested  pairs  of  calls  to
       tickit_renderbuffer_save(3) and tickit_renderbuffer_restore(3). Both functions only affect the subsequent
       drawing   operations;   they   do   not   affect   existing   stored   content,   nor  the  behaviour  of
       tickit_renderbuffer_flush_to_term(3).

       These functions return no value.
