OVERVIEW

	Four new functions for line segments.
	Various improvements; three minor bug fixes.

NEW FUNCTIONS

	density.psp
		kernel estimate of intensity of a line segment pattern.
	
	endpoints.psp
		extracts endpoints of a line segment pattern.

	pairdist.psp
	crossdist.psp
		compute distances between pairs of line segments

IMPROVEMENTS/ENHANCEMENTS

	density.ppp
		ksmooth.ppp has been renamed density.ppp
		so that it is now a method for the generic "density".

		The old ksmooth.ppp is now deprecated.

		density.ppp now works faster in the case edge=FALSE.
		
	demo(spatstat)
		Includes more examples

	Various help files improved.

BUGS

	[1] eval.im

		Fixed.

	[2] eval.fv
		Similar bug to [1]. Fixed.

	[3] plot.im and image.im
		Ignored arguments 'main' and 'sub'.
		Fixed.
