 * $Log: widget_icon.c,v $
 * Revision 1.23  2006/02/25 13:36:33  geronet
 * updated indent.sh, applied coding style
 *
 * Revision 1.22  2006/01/23 06:17:18  reinelt
 * timer widget added
 *
 * Revision 1.21  2006/01/22 10:01:09  reinelt
 * allow 'static' icons with speed=0
 *
 * Revision 1.20  2005/12/18 16:18:36  reinelt
 * GPO's added again
 *
 * Revision 1.19  2005/11/06 09:54:43  reinelt
 * fixed icon size removed, uses XRES & YRES (I hope this doesn't lead to problemes...)
 *
 * Revision 1.18  2005/11/06 09:17:20  reinelt
 * re-use icons (thanks to Jesus de Santos Garcia)
 *
 * Revision 1.17  2005/05/08 04:32:45  reinelt
 * CodingStyle added and applied
 *
 * Revision 1.16  2005/01/18 06:30:24  reinelt
 * added (C) to all copyright statements
 *
 * Revision 1.15  2004/11/28 15:50:24  reinelt
 * Cwlinux fixes (invalidation of user-defined chars)
 *
 * Revision 1.14  2004/06/26 12:05:00  reinelt
 *
 * uh-oh... the last CVS log message messed up things a lot...
 *
 * Revision 1.13  2004/06/26 09:27:21  reinelt
 *
 * added '-W' to CFLAGS
 * changed all C++ comments to C ones
 * cleaned up a lot of signed/unsigned mistakes
 *
 * Revision 1.12  2004/06/20 10:09:56  reinelt
 *
 * 'const'ified the whole source
 *
 * Revision 1.11  2004/03/11 06:39:59  reinelt
 * big patch from Martin:
 * - reuse filehandles
 * - memory leaks fixed
 * - earlier busy-flag checking with HD44780
 * - reuse memory for strings in RESULT and hash
 * - netdev_fast to wavid time-consuming regex
 *
 * Revision 1.10  2004/03/06 20:31:16  reinelt
 * Complete rewrite of the evaluator to get rid of the code
 * from mark Morley (because of license issues).
 * The new Evaluator does a pre-compile of expressions, and
 * stores them in trees. Therefore it should be reasonable faster...
 *
 * Revision 1.9  2004/03/03 04:44:16  reinelt
 * changes (cosmetics?) to the big patch from Martin
 * hash patch un-applied
 *
 * Revision 1.8  2004/03/03 03:47:04  reinelt
 * big patch from Martin Hejl:
 * - use qprintf() where appropriate
 * - save CPU cycles on gettimeofday()
 * - add quit() functions to free allocated memory
 * - fixed lots of memory leaks
 *
 * Revision 1.7  2004/02/15 21:43:43  reinelt
 * T6963 driver nearly finished
 * framework for graphic displays done
 * i2c_sensors patch from Xavier
 * some more old generation files removed
 *
 * Revision 1.6  2004/02/07 13:45:23  reinelt
 * icon visibility patch #2 from Xavier
 *
 * Revision 1.5  2004/02/04 19:11:44  reinelt
 * icon visibility patch from Xavier
 *
 * Revision 1.4  2004/01/30 20:57:56  reinelt
 * HD44780 patch from Martin Hejl
 * dmalloc integrated
 *
 * Revision 1.3  2004/01/29 04:40:03  reinelt
 * every .c file includes "config.h" now
 *
 * Revision 1.2  2004/01/23 07:04:39  reinelt
 * icons finished!
 *
 * Revision 1.1  2004/01/23 04:54:03  reinelt
