// Name:        src/generic/wizard.cpp
// Purpose:     generic implementation of wxWizard class
// Author:      Vadim Zeitlin
// Modified by: Robert Cavanaugh
//              1) Added capability for wxWizardPage to accept resources
//              2) Added "Help" button handler stub
//              3) Fixed ShowPage() bug on displaying bitmaps
