	* gtk/gtkcolorsel.c (gtk_color_selection_set_current_alpha):
	Fix conversion from float to int so that we don't get
	skew in the int => float => int roundtrip.
	(#58120, reported by Vitaly Tishkov). Also fix problem
	where if no alpha was set, the returned alpha
	from (say) set_current_alpha() was returned as 1, not 65535.
