    quartz-font: Fix extents computation for colored bitmaps

    quartz: Support rendering colored bitmap fonts
    
    In _cairo_quartz_cg_glyphs prefer to use CTFontDrawGlyphsPtr over
    CGContextShowGlyphsWithAdvances when available, since the former is
    also capable of rendering colored bitmap glyphs. Colored bitmap glyphs
    are for example found in the Apple Color Emoji font.
    
    Partially fixes colored-glyph.
    
    Based on a patch by: Kristian Rietveld <kris at loopnest.org>

    quartz: Cleanup computation of glyph advances
    
    Just compute them from the glyph positions, without keeping track of
    the previous values.

    quartz: Avoid misaligned types when computing advances
    
    The CGSize type has a stricted alignment than CGGlyph. Although this
    has not been verified, this would have caused misaligned accesses,
    which could be a problem on ARM platforms.

    quartz: Improve the explanation of text transforms management
    
    The text transforms must be handled wit care, to avoid triggering
    bugs, especially when the text is being used as a mask.
    
    The explanation of the issue was removed in
    9c0d761bfcdd28d52c83d74f46dd3c709ae0fa69.

    quartz-font: Expose the CTFont reference for internal usage
    
    The CTFont reference can be used by the Quartz surface to invoke
    drawing APIs.

    quartz-font: Improve CTFont handling
    
    Instead of getting the CTFont for each glyph, reference it only once
    for the whole lifetime of the font face.

    quartz-font: Make CoreText dynamic detection more robust
    
    Apparently Tiger (10.4) has received its own special version of
    CoreText and the dynamic linker might attempt to use it.
    Unfortunately it is incompatible with the CoreText API definition used
    in 10.5+.
