// Constraint is that ks.h cannot be included in the idl file. The directives below ensure that
// 1) KSTOPOLOGY_CONNECTION is locally defined for purposes of building the idl file itself.
// 2) An app can include vidcap.h and ks.h in either order.
// 3) The structure definition for KSTOPOLOGY_CONNECTION does not show up in vidcap.h since ks.h gets included.
// Look at vidcap.h to understand exactly what gets generated.
