assvg_compound()

static void assvg_compound ( stringbuffer_t *  sb, const LWCOMPOUND *  icompound, int  relative, int  precision  )

static

if the compound curve does not start with a line, we need to skip the first point since it is the same as previous point of previous curve

in theory this should never happen
