Ok, I implemented the complete proposed solution -- hiding the visuals in the
connection block and adding the visuals through the Composite extension.

However, this breaks the Render extension, and any other subsystem which expects
to find all of the available visuals in the (exposed) Screen/Depth/Visual
structures which are part of the public Xlib API.

I propose that we go back to the old solution where these new visuals *are*
exposed in the core protocol and that we do provide the Xlib environment
variable hack to hide them for certain applications.  I will reduce the set of
new visuals to just the depth-32 ARGB visual so that applications don't
accidentally stumble upon the depth 24 RGB visual which just runs slowly.

Given that Composite will be disabled by default, I think this will provide
sufficient transition notice for any broken applications, and provide people who
do enable the extension to work around any troubles they do find in the meantime.
