This routine starts a new graphics buffering context. A matching call to the routine AST_EBUF should be used to end the context.

CALL AST_BBUF( THIS STATUS )

THIS = INTEGER (Given)

STATUS = INTEGER (Given and Returned)

• The nature of the buffering is determined by the underlying graphics system (as defined by the current grf module). Each call to this routine to this routine simply invokes the astGBBuf function in the grf module.
