Member data containing clipping box have to be updated not only when the clipping region is explicitly changed by SetClippingRegion()/DestroyClippingRegion() but also when wxDC coordinates are transformed with SetDeviceOrigin(), SetLogicalOrigin(), SetUserScale(), SetLogicalScale(), SetTransformMatrix() or ResetTransformMatrix(). When any of these functions is called then clipping box data are marked as invalid and updated by recalculating extents of the clipping region in new coordinates at nearest call to GetClippingBox(). Closes #17646.
