2006-10-20 Kevin Cozens <kcozens@cvs.gnome.org> * plug-ins/script-fu/scheme-wrapper.c: Moved the MIN and MAX entries for image size and resolution to script_constants structureas they are not deprecated constants. * plug-ins/script-fu/scripts/script-fu.init: Removed CR in line endings. * plug-ins/script-fu/scripts/*.scm: Fixed a number of regressions that snuck in during the last big update of the scripts. This update reduces the number of differences to the original scripts (other than formatting). Some additional formatting changes in a few scripts. Updates to use colour names in register block where possible. Fixed a bug in burn-in-anim.scm. Minor cleanup of font-map.scm. Simplified the bug fix in tile-blur.scm.
