Notes on how to do selection like Microsoft Internet Explorer

[Assume LTR for the moment]

	For the purposes of this algorithm, spaces are separate words

	Two flags:
		greedy_start_word
		greedy_end_word


	- Init: greedy_start_word = TRUE; greedy_end_word = FALSE

On mouse movement:

	- if new position is within anchor word,
		
		begin_select = exact anchor point
		end_select = exact position

		if we are in different word than before (ie., we just
		entered	the anchor word for the second time),

			greedy_start_word = FALSE

	  else

		if movement was away from anchor point

			if we are in a different word than before
				greedy_end_word = TRUE

		else

			greedy_end_word = FALSE

		begin_select = exact anchor;
		end_select = exact position;

		if (greedy_start_word)
			if (position > anchor) /* FIXME RTL? */
				begin_select = beginning of anchor_word
			else
				begin_select = end of anchor_word

		if (greedy_end_word)
			if (position > anchor) /* FIXME RTL? */
				end_select = end of current word
			else
				end_select = beginning of current word
