D3D7 ScissorRect Equiv?

I know OGL has scissors as does DX9 but is there a way to have these in DirectX7 without using ClipPlanes? It has been mentioned that can I use Viewports (Not BMAX viewports *REAL* viewports) but that won't work unless I tweak the projection matrix for each port.

Any ideas for fast clipping of rectangular areas in D3D7?

Anyone?

Look into 'Clip Lists' and IDirectDrawSurface7::SetClipper()

Thanks Tom.
