plclear: Clear current (sub)page 

DESCRIPTION:

	Clears the current page, effectively erasing everything that have been
	drawn.	This command only works with interactive drivers; if the
	driver does not support this, the page is filled with the background
	color in use. If the current page is divided into subpages, only the
	current subpage is erased.	The nth subpage can be selected with
	pladv(n). 

SYNOPSIS:
