* Revision 1.6 2005/01/18 06:30:24 reinelt
|
|
* added (C) to all copyright statements

|
*
|
|
* Revision 1.5 2004/06/26 12:05:00 reinelt
|
|
*
|
|
* uh-oh... the last CVS log message messed up things a lot...
|
|
*
|
|
* Revision 1.4 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 1.3 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 1.2 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 1.1 2004/01/18 21:25:16 reinelt
|
|
* Framework for bar widget opened
