GEGL

GEGL (Generic Graphical Library) is a programming library under development for image processing applications. It is mainly developed to bring deep color support (ie. support for images with more than 8 bits per color channel) to GIMP, but may be used by other software too.
GEGL uses trees of image operations (called operators) chained together, driven by an on-demand model where work is done only as required. (This enables potential features like having very quick previews while editing, and doing the same operations in full resolution for the final image in the background, like xRes.) The operators can be simple, such as "add" (taking two inputs) or "premultiply by alpha" (taking one input), or more complex, such as colorspace conversions.
GEGL will also provide a generic way to deal with color spaces. The idea is that the fundamental operations are abstracted away from the program in question; GEGL provides optimized and powerful (optionally with SIMD support) treatment of arbitrary color data. This enables an application to efficiently support a wide range of color spaces (from 8-bit RGB to full floating point CMYK) with minimal extra application code.
GEGL was originally intended for use with GIMP 2.0, but it is still far from finished. See also Second-system effect.
