Repair

// ============================================================================
//  repair -- C++ ActiveX (COM) port, following
//  examples/activex/repair/repair.vbs
//
//  Fixes a damaged PDF with a SINGLE call: ConvertFile(..., ctNormalize).
//  Normalising a file forces the engine down its repair path, and
//  GetInRepairMode afterwards reports which repair strategy it actually needed.
//
//  The AX ConvertFile is the 7-argument form (ends at OwnerPwd) -- the flat
//  API's trailing OnFontNotFound / OnReplaceICCProfile callback pointers have
//  no place on a COM signature; they are connection-point events instead.
// ============================================================================
