Hi, I've just done more-or-less exactly the same this
weekend with a couple of differences.

I've merged all the creation surface code into a
single createSurface function that is called with
different parameters/flags to create a backbuffer,
PlainOffscreenSurface or rendertarget etc...

This should mean that you only require one call-back
function for CreateDevice in WineD3D.

I'll merge your patch with what I've got and see how
it goes.

As soon as I'm happy with how wine's and directX work
I can stop duplicating what you've done and start
moving onto a more co-operative development, or moving
DirectX8 over to using WineD3d.


So far I can run Pirates! and a few of the demos from
http://www.codesampler.com/dx9src.htm, but without
textures.

Pirates uses DirectX 9c but doesn't do anything too
fancy and runs without crashing so it seems good for
testing.

Many of the demos at
http://www.codesampler.com/dx9src.htm have OpenGL
versions and since I don't know OpenGL or DirectX (but
can hack a good Dos demo) it seemed a good place to start.
