NEWS/Changelog

1.3-2	(under development)
    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	(under development)
    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.
