[vtkusers] vtk 4.2 compilation error, linux, vtkBMPRead.cxx

[Dongbai Guo]

In fact, just found that the fix is easy:
Simply swap the two parameters:
from:
       self->GetFile()->seekg(self->GetFile()->tellg() + streamSkip0, 
ios::beg);
to:
     self->GetFile()->seekg(streamSkip0 + self->GetFile()->tellg(), 
ios::beg);
 There are some similiar error elsewhere.
