Hi all - we are trying to render to offscreen memory (on Win32), then composite result with other graphics. This requires:
1. Alpha rendered to target 32 bit buffer
2. non-premultiplied alpha
In spite of our best efforts, Bill doesn't want us to do this. Any suggestions? Thanks.

It'll probably be slow but try using the Accumulation Buffer.

I thought there was a WGL pbuffer extension now. If you're not getting the resources you want you might try picking a pixel format with less capabilities in another area (depth buffer, for instance), or using a smaller resolution which will free up some more video card resources.
