Dots - consistency across terminals

[Ethan A M. <merritt@u.washington.edu>]

The postscript and pdf terminals plots dots as a zero length vector
using the current linewidth. This means that 
	plot <foo> with dots lw 1, <baz> with dots lw 10
produces two different dot sizes.

Other terminals do not do this. Should they?
