PGPLOT Module: PGEBUF -- end batch of output (buffer)


A call to PGEBUF marks the end of a batch of graphical output begun
with the last call of PGBBUF. PGBBUF and PGEBUF calls should always
be paired. Each call to PGBBUF increments a counter, while each call
to PGEBUF decrements the counter. When the counter reaches 0, the
batch of output is written on the output device.
