I'm trying out rotation with Direct3D using the d3dx9 unit (and dll), however my object (a quad made out of 2 triangles) refuses to move an inch... I tried all sorts of combinations and positions, but it just refuses to work...

I am using this FVF:
const D3DFVF_CUSTOMVERTEX = ( D3DFVF_XYZRHW or D3DFVF_TEX1);
and my guess is that the D3DFVF_XYZRHW isn't supported in rotation...
