    tdf#130478 add direct dash paint in cairo
    
    Make use of mentioned task's 1st commit now
    and implement direct dashing for cairo. All
    the data is now available (that was the work),
    make use of it.
    Keeping a local static bool to control it, so
    later if needed can be switched on/off e.g
    using some global var/setting.
    Cairo will now do buffering of complex polygon
    data in cairo path data (from some compexity
    on and timer/mem-controlled), but not dismantle
    to own, stroked data.
    With bDoDirectCairoStroke disabled, the dis-
    mantled data will be buffered - more mem, but
    should also help - at least it gets reused
    now that it is possible to keep it at the
    original geometry (incoming polygon) at all
