Integrating a filter into the VirtualDub source tree

Most external filters can be easily imported into the VirtualDub source tree with only minor modifications. The programming model is very similar, so these are the few necessary changes:

Some of VirtualDub's internal filters can also be removed similarly to create external filters. Others, such as resize, make use of internal routines in resample.cpp and require that additional routines be lifted out. A few, such as fill, make extensive use of internal interfaces and can't be lifted at all.
