	* src/rendered-value.c (rendered_value_new): Just peek directly
	into the approx_width structure -- everyone else does that.  Take
	worst case of "e", signs, and decimal points into account.

	* src/style.h (StyleFont): Change floats to doubles.  Add more
	approx_width fields.

	* src/style.c (style_font_get_width_pts): Remove.
