[vtkusers] wxWindows/VTK

I've implemented these changes, and it's made no difference.  I have the 
static vtk libs as far as I can tell, and I'm including the following 
libs (using wxWin 2.4.0):

comctl32.lib rpcrt4.lib winmm.lib advapi32.lib wsock32.lib wxmsw.lib 
vtkCommon.lib vtkRendering.lib vtkGraphics.lib vtkFiltering.lib 
vtkImaging.lib vtkHybrid.lib vtkIO.lib vtktiff.lib vtkjpeg.lib 
vtkzlib.lib vtkfreetype.lib vtkftgl.lib opengl32.lib glu32.lib

The first five libs are recommended on the wxwindows page, the next is 
the one for the wxWin release non-dll implementatin, then the slew of 
vtk and opengl things I need.

The errors I get are all about dll usage, and as far as I can tell, I've 
got neither vtk nor wxwin set up to be used as a dll.  If someone has a 
project file that is working and could be sent to me, I would be 
incredibly grateful.  I've pasted a copy of my errors below, so that it 
can be seen what's happening.

Compiling...
