+/* XPM plugin version 1.2.7 */
+
+/*
+1.2.7 fixes saving unused transparency (bug #4560)
+
+1.2.6 fixes crash when saving indexed images (bug #109567)
+
+1.2.5 only creates a "None" color entry if the image has alpha (bug #108034)
+
+1.2.4 displays an error message if saving fails (bug #87588)
+
+1.2.3 fixes bug when running in noninteractive mode
+changes alpha_threshold range from [0, 1] to [0,255] for consistency with
+the threshold_alpha plugin
+
+1.2.2 fixes bug that generated bad digits on images with more than 20000
+colors. (thanks, yanele)
+parses gtkrc (thanks, yosh)
+doesn't load parameter screen on images that don't have alpha
+
+1.2.1 fixes some minor bugs -- spaces in #XXXXXX strings, small typos in code.
+
+1.2 compute color indexes so that we don't have to use XpmSaveXImage*
+
+Previous...Inherited code from Ray Lehtiniemi, who inherited it from S & P.
