Added support for transforming homogenous W geometry into world geomtry

This is an update on the previous pull request #188.

Thanks @dkollmann! I will take a look at this soon.

Also FYI if you try this code with Black & White, things will have a blue tint. This is because the water plane which should be rendered before all the other geometry, is rendered on top of it instead of behind the other geometry.

I made some fixes. Of course lpD3DMatrix has to be replaced, after getting the game camera properties from it.
I added an option to disable the lighting which is needed when DdrawConvertHomogeneousW is true but DdrawConvertHomogeneousToWorld is false. At least for Black & White.

The force push was just an update on the commit comment.

For some reason when I add this DdrawConvertHomogeneousW = 1 line to the ini file I just get the following:

Ok, I figured this out. You have to set DdrawDisableLighting = 1 for Black & White.

My only last comment is that I prefer to create a struct and add it to the IDirect3DDeviceX.h file rather than a whole new RednerData class for the DdrawConvertHomogeneous settings/matrices. Since the code is in IDirect3DDeviceX.cpp the settings should be in IDirect3DDeviceX.h.

Other than that, I think this is about ready to merge.

Ah okay, I created the RenderData.h, because it was not possbile to include the device header in the DebugOverlay.cpp file.

DebugOverlay.h already has #include "ddraw.h", which includes IDirect3DDeviceX.h. So it is already covered.
