Kevin Cozens 590c4d0b9f Moved the MIN and MAX entries for image size and resolution to
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.
