Immediate plans:
* figure out why image quality is not as good as Kodak supplied tools
* figure out appropriate colour correction (white balance)
* write a light tiff library for reading KDC files
* include support for other .kdc file formats (ie. from DC40/DC50)
* write a kdctopnm tool for use with the netpbm package

Old plans:
* improve contrast enhancement (work with intensity, not individual colors)
* optimize getScanLine*() in GImageComponent
* write cropping filter
* write red-eye reduction algorithm
* decode format of files from known digital cameras (DC120 and CP950)
* rewrite the gamma correction equations to use all integer math
* make TIFF compression scheme work
* make contrast enhancement and white balance work with all image types
* make command line interface as similar as possible to 'convert'
* update GFilter_Rotate to handle non-90 degree angles
