return the minimum distance bw this and the point (px,py)

compute the minimum distance bw the point (px,py) and this. Optionnaly, store the nearest point in (rx,ry)

Parameters

px	x coordinate of the point
py	y coordinate of the points
rx	pointer to x coorinates of the nearest point (can be NULL)
ry	pointer to y coorinates of the nearest point (can be NULL)
