commit 77dc491d3b0c1429801ec839e7afab0fbef6a7fc

    output: Use Cairo and Pango to draw charts, instead of libplot.
    
    This paves the way for adding support for charts to the PSPPIRE GUI, since
    Cairo can render to a window in GTK+ whereas libplot cannot.
    
    I am aware of the following regressions versus the state before this
    commit:
    
    1. Alignment of text in charts on the baseline is not properly implemented.
       This makes the labels in pie charts look funny.
    
    2. Chart titles are drawn in the same font size as other chart text.
    
    3. Building without Cairo and Pango is broken.
    
    4. The postscript output driver (as opposed to the cairo output driver in
       PostScript output mode) no longer supports charts.
    
    I plan to fix #1, #2, and #3.  #4 is fixable too, but I don't know whether
    it is worth it; I might prefer to delete the postscript output driver
    altogether.

    output: Make chart geometry the responsibility of the output driver.
    
    Currently, with libplot, all charts have the same geometry, because
    libplot allows us to reasonably set the dimensions of the drawing area
    to the same 1000x1000 size.  But cairo will produce strangely scaled
    results if we attempt to do the same thing there (distorted font sizes,
    etc.).  So make the output drivers responsible for setting up the chart
    geometry, so that the output drivers can tell the chart drawing routines
    the size of the drawing area.

    charts: Use numeric colors instead of color names.
    
    Cairo doesn't support color names, so this will ease the transition.
