+Load
+====
+Photoshop 2.0 and lower files are not supported due to lack of
+file specs and test files.
+
+Add text names for color modes
+
+Parasite for layer blending ranges per channel?
+
+Read & use global mask data
+
+Check for block over-run in read_channel_data
+
+Process errors from readers in read_channel_data
+
+Invert layer mask - channel_set_show_masked or invert mask + parasite
+
+decode more image resources
+
+Read in layer resources and process adjustment layers etc.
+add parasites as required - should be similar to image resources
+
+add layer support for:
+
+Text layers
+
+vector masks
+
+Image resources:
+================
+
+1005 - resolution
+ width and height units dropped.
+
+1007 - Display info
+ save color space & color as parasite if unable to display.
+
+1008 - caption - Add to XMP data block.
+
+1025 - Working path (not saved) - Load
+
+1026 - Layers Group Info - ?Load
+
+1033 1036
+ Better error handling for Jpeg decompression. Check for JPEG being included
+ Custom error function.
+
+1041 - Honour ICC untagged option
+
+2000-2998 - Paths
+ Add initial fill rule and clipboard parasites.
+
+2999 - Clipping path
+ Add as parasite to path record.

+ * Revision history:
+ *
+ * 2000.02 / v1.0 / Monigotes
+ * First version.
+ *
+ * 2003-05-10 Pedro Gimeno <pggimeno@wanadoo.es>
+ * - Cleaned up and GNUstylized.
+ * - Translated all comments and vars in Spanish to English.
+ *
+ * 2005-2-11 Jay Cox <jaycox@gimp.org>
+ * Rewrote all the code that deals with pixels to be stingy with
+ * memory and operate on tile-size chunks. Create a flattened
+ * copy of the image when necessary. Fixes file corruption bug
+ * #167139 and memory bug #121871
+ *
+ * 2006-03-29 Guillermo S. Romero <gsr.bugs@infernal-iceberg.com>
+ * - Added/enabled basic support for layer masks based in psd.c
+ * and whatever was already here.
+ * Layers that are not canvas sized need investigation, here
+ * or in the import plugin something seems wrong.
+ * - Cosmetic changes about the debug messages, more like psd.c.
