Thank you, that will be useful :)

I believe it was a performance hack for web pages with several layers
of partial transparency. At the time we had an evil test case which
saw great speed-up with this hack. If the shm stuff isn't available,
I'm sure we'll revert to ordinary rendering (that's basically what the
"error" message is about). So nothing should break.

And you may get a slightly different answer from the people who
actually know this part of the code :)
