    Expose colour_mix() to backends (and others)
    
    Quite a few backends currently generate colours by multiplying the
    foreground colour by a fraction, effectively mixing it with black.  On a
    black background, this might be reasonably replaced by mixing the
    background colour with white, but that's rather arithmetically fiddly.
    Happily, I already have a function for that and just need to expose it.

    Tracks: Set the grid colour based on others
    
    COL_GRID used to be mid-way between the usual COL_BACKGROUND and
    COL_TRACK_BACKGROUND.  But then I changed mkhighlight() so that it
    didn't make COL_BACKGROUND so dark and that made the grid lines
    indistinguishable from the track background.
    
    Now COL_GRID is generated from COL_BACKGROUND and COL_TRACK_BACKGROUND
    so as long as those are sufficiently distinct from each other, COL_GRID
    will be distinct from both of them.
