    o   fix SET_VECTOR_ELT issue for R 2.9.0+

1.4-4   (2008-10-17)
    o   adapt to changes in R-devel (2.9.0-to-be), clean up warnings

1.4-3   (2008-07-21)
    o   make the use of an invalid font non-fatal

    o   allow Cairo to compile on some older systems that don't have

1.4-2   (2008-04-03)
    o   adapt to even more changes in R 2.7

1.4-1   (2008-03-14)
    o   adapt to R 2.7 changes

1.4-0
    o   fix DPI detection in X11 back-end and use 90dpi as a fallback

    o   fix cra settings to be closer to what other devices use

    o   CairoX11 no longer fixes DPI to 72, "auto" is now the default.
        In addition, CairoWin and CairoX11 allow additional arguments
        to ba passed to Cairo.

1.3-5   (2007-08-27)
    o   adapt to const char* CHARs in R-devel

    o   fix a bug in CairoSVG (wrong argument name)

    o   fix a bug in CairoPS (units were not set to "in" and
        width/height had no defaults)

    o   fix unintentional doubling of the .ps suffix

1.3-4   (2007-05-10)
    o   more fixes in flag-guessing

    o   some vector backends (e.g. PDF, SVG) were falling back to
        bitamp rasterization, we try to prevent this

    o   address expose issues with some X11 servers

    o   add CairoSVG wrapper

    o   add an unified way to register back-ends and get a list of all
        supported types.

    o   add Cairo.capabilities() function

1.3-3   2007-04-25
    o   improve detection of cairo and its dependencies

    o   work around missing API such that cairo 1.0 can be used.
        However, it is strongly encouraged to use cairo 1.2 or
        possibly 1.4 as they contain important bugfixes.

    o   fix page numbering to start at 1 (was 0) and update
        documentation correspondingly

1.3-2   2007-04-18
    o   added format autodetection for tiff and png. The 32-bit
        version of either format is used if the background
        is not opaque.

    o   fixed bug in the value returned by Cairo

    o   added type and file attributes to the Cairo object

    o   added (hidden, experimental) functions that allow direct
        modification of image content in Cairo (.image, .ptr.to.raw
        and .raw.to.ptr)

1.3-1
    o   change semantics of canvas and bg to match other devices:
        canvas is used by devices that don't support any kind
        of transparency in case bg is translucent

    o   fixed data ordering issues in TIFF and JPEG output

    o   added "compression" parameter to TIFF back-end which
        now defaults to LZW compression

1.3-0
    o   add support for canvas and dpi specification

    o   allow backends to detect native resolution

    o   add support for custom parameters (e.g. quality for jpeg)

1.2-1
    o   improve rendering on bitmap devices by aligning straight lines
        to the pixel grid and adding bleed to such fills.

    o   added wrappers that take exactly the same parameters as
        existing devices such as png, jpeg, pdf, postscript, X11 or
        windows and map them to calls to Cairo. They can be used to
        replace native devices by Cairo without the need to change
        existing code.

    o   added namespace

1.2-0
    o   additional interactive back ends: X11 (XLib) and win (Win32)

    o   enhanced back-end API to support interactive back-ends

    o   change default backgroud color to "white", because
        alpha-blending doesn't work properly in cairo when painting on
        purely transparent background.

    o   change the way filenames are interpreted, use multi-file
        printf convention as other devices do.

    o   added support for jpeg and tiff image formats

1.1-0
    o   additional file/stream back-ends: svg, ps

    o   enhanced back-end API

1.0-0
    o   fixed function names to not conflict with GDD

0.1-5
    o   added R connections patch support at config time.
