/*
* PSD Export Plugin version 1.0 (BETA)
* This GIMP plug-in is designed to export Adobe Photoshop(tm) files (.PSD)
*
* Monigotes
*
* If this plug-in fails to export a file which you think it should,
* please tell me what seemed to go wrong, and anything you know
* about the image you tried to export. Please don't send big PSD
* files to me without asking first.

/*
* 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.
