GEGL (Generic Graphics Library) is a graph based image processing framework.

GEGL provides a graph based API and framework to do demand driven, cached, non destructive image editing of sparse storage of larger than RAM images - using CPU or GPU
processing. Through babl it provides support for a wide, and extendable, range of color models and pixel storage formats for input and output.

To build gegl-0.3.0 you will also need babl-0.1.12 and a recent version of glib, follow see the output of the configure script for details.

Changes in this release:

• Improvements to thread safety and parallelism. • Lower overhead graph travesal due from rewrite of visitors • OpenCL support now enabled by default when detected. • Experimental multithreading, enable by setting GEGL_THREADS= in the environment. • Experimental mipmap rendering, which permits transparent rendering of previews on smaller sized versions, enable by setting GEGL_MIPMAP_RENDERING=true in the environment. • Website/documentation: split website in more pages, added op gallery and API browser.
• Operations:
• new operations: alien-map, antialias, apply-lens, bilateral-filter, bump.map, cartoon, channel-mixer, color-enhance, color-exchange, color-reduction, color-rotate, convolution-matrix, copy-buffer, cubism, deinterlace, diffraction-patterns, distance-transform, displace, edge, emboss, engrave, exposure, fractal-trace, high-pass, image-compare, illusion, invert-gamma, lens-flare, linear, linear-gradient, mosaic, motion-blur-circular, motion-blur-zoom, noise-cell noise-cie-lch, noise-hsv, noise-hurl, noise-pick, noise-rgb, noise-simplex, noise-spread, n-point deformation ops, oilify, panorama-projection, photocopy, plasma, radial-gradient, red-eye-removal, scale-size-keep-aspect, softglow, stretch-contrast, texturize-canvas, tile-glass, tile-seamless, tile-paper, tile, warp, whirl-pinch, wind, cache, cast-format, lcms-from-profile, npy-save, webp-load, webp-save, scale-ratio, scale-size, seamless-clone, sinus, supernova, value-propagate, video-degradation • reimplementation of gaussian-blur faster and more accurate • support for using URIs in image loaders • Buffer:
• New default tile backend, doing disk writes in a separate thread.

do you really need libraw >= 0.16.0?

I have some trouble with the recent version in Ubuntu Trusty - 0.15.4. You know - dependency nightmare.:'(

If it compiles and thus probably works with an older version - I see no reason to make the check as strict as it is, what version of libraw does your version of ubuntu provide?
