Not to a special one, to a free one. I have started working on some Xlib
server-side canvas stuff since getting back from LWE and it will only
work with XFree because that's the only one where I have the sources.
Using standard client-side X(Q)Image code is *slow* because of having to
do copies to update, you'll end up with something around the performance
of the Gnome canvas - which despite the hype is unusable in realtime
stuff. They are even trying to use it for AA fonts in their text editor
and you type a line, wait, type a line, wait, etc... it's just plain
wrong. If you want high performance graphics you *have* to do it in the
server and the only free one is Xfree. There are hacks like MITSHM, but
I have found them to be unsuitable for multiple windows.
That doesn't mean a alternative can't be done in the client for
compatibility with other servers and net usage, but it will be much,
much slower. I am not going to do bad solutions to stay compatible with
closed source, commercial code. I *will* use a MIT license tho, so if
they want to use it they are free to do so.
