Fix dashed/dotted regression caused by multi-style text decoration patch.
If you fall through from TextDecorationStyle[Dotted, Dashed] to
TextDecorationStyleDouble, then obviously double lines will be drawn.
Also, change code to reuse as much code as possible rather than duplicate
approximately the same thing three times.
There should be no functional changes other than the regression fix.
