 * $Log: drv_MatrixOrbital.c,v $
 * Revision 1.21  2004/03/19 09:17:46  reinelt
 *
 * removed the extra 'goto' function, row and col are additional parameters
 * of the write() function now.
 *
 * Revision 1.20  2004/02/14 11:56:17  reinelt
 * M50530 driver ported
 * changed lots of 'char' to 'unsigned char'
 *
 * Revision 1.19  2004/01/29 04:40:02  reinelt
 * every .c file includes "config.h" now
 *
 * Revision 1.18  2004/01/23 07:04:22  reinelt
 * icons finished!
 *
 * Revision 1.17  2004/01/23 04:53:50  reinelt
 * icon widget added (not finished yet!)
 *
 * Revision 1.16  2004/01/22 07:57:45  reinelt
 * several bugs fixed where segfaulting on layout>display
 * Crystalfontz driver optimized, 632 display already works
 *
 * Revision 1.15  2004/01/21 12:36:19  reinelt
 * Crystalfontz NextGeneration driver added
 *
 * Revision 1.14  2004/01/20 15:32:49  reinelt
 * first version of Next Generation HD44780 (untested! but it compiles...)
 * some cleanup in the other drivers
 *
 * Revision 1.13  2004/01/20 14:25:12  reinelt
 * some reorganization
 * moved drv_generic to drv_generic_serial
 * moved port locking stuff to drv_generic_serial
 *
 * Revision 1.12  2004/01/20 12:45:47  reinelt
 * "Default screen" working with MatrixOrbital
 *
 * Revision 1.11  2004/01/20 05:36:59  reinelt
 * moved text-display-specific stuff to drv_generic_text
 * moved all the bar stuff from drv_generic_bar to generic_text
 *
 * Revision 1.10  2004/01/20 04:51:39  reinelt
 * moved generic stuff from drv_MatrixOrbital to drv_generic
 * implemented new-stylish bars which are nearly finished
 *
 * Revision 1.9  2004/01/18 21:25:16  reinelt
 * Framework for bar widget opened
 *
 * Revision 1.8  2004/01/15 07:47:02  reinelt
 * debian/ postinst and watch added (did CVS forget about them?)
 * evaluator: conditional expressions (a?b:c) added
 * text widget nearly finished
 *
 * Revision 1.7  2004/01/14 11:33:00  reinelt
 * new plugin 'uname' which does what it's called
 * text widget nearly finished
 * first results displayed on MatrixOrbital
 *
 * Revision 1.6  2004/01/11 18:26:02  reinelt
 * further widget and layout processing
 *
 * Revision 1.5  2004/01/11 09:26:15  reinelt
 * layout starts to exist...
 *
 * Revision 1.4  2004/01/10 20:22:33  reinelt
 * added new function 'cfg_list()' (not finished yet)
 * added layout.c (will replace processor.c someday)
 * added widget_text.c (will be the first and most important widget)
 * modified lcd4linux.c so that old-style configs should work, too
 *
 * Revision 1.3  2004/01/10 17:34:40  reinelt
 * further matrixOrbital changes
 * widgets initialized
 *
 * Revision 1.2  2004/01/10 10:20:22  reinelt
 * new MatrixOrbital changes
 *
 * Revision 1.1  2004/01/09 17:03:07  reinelt
 * initiated transfer to new driver architecture
 * new file 'drv.c' will someday replace 'display.c'
 * new file 'drv_MatrixOrbital.c' will replace 'MatrixOrbital.c'
 * due to this 'soft' transfer lcd4linux should stay usable during the switch
 * (at least I hope so)
