The main reason people might need it, even if they were not toolkit developers, is so that they could trace apparent bugs or other misfeatures that they had encountered in some application. In my case, I was looking for some unacceptable CPU usage in Opera, which is built on top of QT. I traced that down to a bug/misfeature in libxft, which I reported on this list on Nov 26th under the Subject "LibXft : xftglyphcore woes", hoping to catch the eye of the libxft developers (sadly, noone responded). Essentially, libxft was making a meal out of its anti-aliasing, and I proposed a patch which at least cured the symptoms. In a subsequent thread "2D antialiasing?" on this list, I was bemoaning the fact that antialiasing by that method would waste huge amounts of bandwidth if the client were separated from the Xserver by some slow network, and someone claimed to me, offlist, that Xrender provided server-side antialiasing. So I wanted to verify that claim. Now that this list has pointed me to Keith Packard's "The X Rendering Extension", I have done a quick scan of that, but can still find no mention of antialiasing. Moreover, that describes the protocol, rather than the libXrender interface that is more conveniently used to access it, >Xrender is in LSB, but is not documented. As a result, >LSB would be willing to help if there's interest in working >up docs. Or, alternatively, listen to an argument that a >library like Xrender actually shouldn't be in the spec, that >only cairo should be exposed. Yes, that would be welcome, but this is not really a Linux problem. It is an Xorg problem. -- Charles H.
