- Relax, Marc. First off, I really like xmosaic, and am hoping version
- 1.0 will be really great! But secondly, I'm not your customer. Who
- cares what I think? Thirdly, it *is* a design decision, probably made
- for all kinds of reasons I'm not aware of which make it a *good* design
- decision. Fourth, of course I read your explanation.

- Well, since you ask... If you're displaying text, it really doesn't
- matter what the maximum size of a window is, so long as you can get at
- least one line on it, right? As the user scrolls through the text, you
- just show different lines, right? But apparently what you're doing is
- turning each document into a giant image of text, and then panning
- through that image, which of course runs you into size problems. This
- is an OK idea if you're building something like HyperCard. But WWW
- isn't always like HyperCard, it tends to mix the ``holy scroller'' model
- with the ``card shark'' model of hypertext. So this approach isn't
- really suited either to WWW or to the X Window System, so far as I can
- see. (The problem with it on X is that is uses big chunks of window
- system resources, typically in one big burst that locks out everything
- else on the screen!) The ``correct'' approach would be more of what
- Viola does, which is to use a text widget. By the way, Viola, the only
- other browser I use, *does* in fact use a text widget, and handles my
- document just fine.
-
- As I said above, maybe I'm missing something?
