Applied patch from David Hodson <hodsond@ozemail.com.au> to fix Bug#33399: 

2000-11-29  Austin Donnelly  <austin@gimp.org>

	* app/curves.c: Applied patch from David Hodson
	    <hodsond@ozemail.com.au> to fix Bug#33399: GIMP crashes when
	    applying curve to Grayscaled image when preview is off.
	    Previously the curves tool attempted a reset when changing
	    image, but didn't correctly do this.  Now it has the
	    (more useful) behaviour of doing a partial reset, where the
	    curve remains the same across multiple invocations, allowing
	    you to apply the same tweak to multiple images.  The internal
	    state relevant to image type/depth is correctly reset,
	    stopping the segfault behaviour seen before.

	    Still no fix for Bug#33403: Curves/Levels Tool does not work
	    on GRAYA-Images.
