// Revision 1.1 2005/01/08 14:54:23 mschimek
30
// *** empty log message ***
32
// Revision 1.5 2001/10/02 17:44:41 trbarry
33
// Changes to be compatible with the Avisynth filter version
35
// Revision 1.4 2001/08/17 19:30:55 trbarry
36
// Fix OBO error in GreedyH Vertical Filter
38
// Revision 1.3 2001/08/17 17:08:42 trbarry
39
// GreedyH performance enhancement:
41
// Unroll loop to support Write Combining in Vertical Filter
42
// (curiously this now peforms better than without V. Filter)
44
// Revision 1.2 2001/07/25 12:04:31 adcockj
45
// Moved Control stuff into DS_Control.h
46
// Added $Id and $Log to comment blocks as per standards
