Ah, that's ok then. I forgot that the other vertex has a specular color, so a 
new vertex type is fine.

Yeah, IDirect3DDevice(1) and IDirect3DExecuteBuffer are a royal pain in the 
ass. Here's some popular rant about it to ease your pain:


I think that a test using execute buffers is a great thing. This interface is 
terribly obscured and we have only one small test for it. You can add it to 
visual.c if you want, or a new file(maybe executebuffer.c, or something), I 
think both places are ok.

You can also try to QueryInterface old IDirect3DDevice* versions from 
IDirect3DDevice7, but I think this doesn't work as the COM theory says on 
Windows. I haven't yet tested the restrictions and implemented them because I 
haven't seen a game yet that depends on them.
