    tdf#79679 vcl: dashed lines show as solid lines when importing EMF files
    
    Backported to 5.1
    
    Issue is a regression in commit 09c722873b2d378d2d155f5f1dd7d8f3fb2012e9.
    (EMF/WMF: fix rendering of pen styles (dash, dot, dashdot, dashdotdot).
    
    I've looked at how the latest version of Word on the Mac works, and it
    turns out that the spacings for the PenStyle enumerations in the LogPen
    objects for all the create pen EMF records are as follows:
    
    * PS_DOT           - ■ □ ■ □ ■ □ ■ □ ■ □ ■
    * PS_DASHDOT       - ■ ■ ■ □ ■ □ ■ ■ ■ □ ■
    * PS_DASHDOTDOT    - ■ ■ ■ □ ■ □ ■ □ ■ ■ ■
    
    (where ■ is the actual filled in area, and □ is the space between the
    filled in areas)
    
    In other words, each dash fills in the space of three dots, and there
    is the one dot worth of empty space between the dashes and dots. Each
    "dot" has a width and height equal to the width specified in the pen.
    
    So basically, we seem to be arbitrarily setting the dot, dash and
    distance lengths arbitrarily, which were reasonable guesses but tended
    to produce very odd lines at different zoom levels.
