- You're missing my point; many applications just aren't useful to their
- users unless the rendering is fast. In fact, many new applications
- have become possible simply by the advances in rendering speeds of
- modern graphics systems. For those applications, it isn't a matter of
- detecting a visual with the given functionality, but it is a matter of
- finding the visual with the given performance. OpenGL guarantees that
- a visual will exist which will have all the functionality, but it
- doesn't provide any way for an application to determine which visuals
- are implemented through hardware, software, or a combination of both.
- At least, if it does provide such a mechanism I haven't found it in
- the man pages or the spec. I haven't read them exhaustively yet,
- though.
