{
// This static contructor was added to make sure we load the proper version of Penimc.dll.
//
// Details:
// P/invoke will use LoadLibrary to load penimc.dll and it will check the current
// application directory before checking the system32 directory where this DLL
// is installed to. If penimc.dll happens to be in the application directory as well
// as the system32 directory we'll actually end up loaded two versions of
// penimc.dll. One that we'd use for P/invokes and one that we'd use for COM.
// If this happens then our Stylus code will fail since it relies on both P/invoke and COM
// calls to talk to penimc.dll and it requires just one instance of this DLL to work.
// So to make sure this doesn't happen we want to ensure we load the DLL using the COM
// registered path before doing any P/invokes into it.
