	ept	EarthPoint to locate.
	ext	How much beyond the edge of domain to search (grid spaces)

Returns:: True if point within domain

bool Domain::withinExt	(	Point &	pt,
		int	ext
	)

Determines whether point is within extended domain

Parameters:

	pt	Point to locate.
	ext	How much beyond the edge of domain to search (grid spaces)

Returns:: True if point within domain

int Domain::wrapLine ( Points & pts )

Wraps line around the edge of a projection. It will adjust either point to draw through projection edge. It returns what correction has been done.

Parameters:

pts

Set of points in line

Returns:: 1=wrap on right, -1 = wrap on left

int Domain::wrapLine	(	Point &	pt1,
		Point &	pt2
	)

Wraps line around the edge of a projection. It will adjust either point to draw through projection edge. It returns what correction has been done.

Parameters:

	pt1	First point
	pt2	Second point

Returns:: 1=wrap on right, -1 = wrap on left

int Domain::zoom	(	Point &	pt,
		float	zfac
	)

Zooms a domain (resets size)

Parameters:

	pt	New centerpoint
	zfac	Zoom factor (>1=zoom in, <1=zoom out)
