Of course not.

I don't actually want a wysywig maths editor (though this doesn't mean
I don't think other people should). Bizarrely, as a result of the
earlier thread around this (and some other coincidental stuff) I've
been doing a lot of things with LaTeX again, and I'm wondering vaguely
about writing a book on just-pre-university applied maths (of course I
never actually will do this). So now what I need is something that
will let me draw scribbly-little-diagrams as scalable things (so not
bitmaps). That turns out to be quite hard to find. I expect you to
have written one by, say, Friday?

(Seriously, I think I want something which will digitize from a tablet
as a bezier which I can then tweak a bit, but I want it to be able to
do things like "attach this line to this line" and "make this line be
vertical", which a lot of applications don't do. As a fallback I think
I may have to learn Asymptote - the idea of using a metafont-derivative
for producing drawings is quite appealing.)

Hmmm. I'm trying to recall your preferred platform, which I think is
Linux.

So will something like InkScape do what you want? I assume that it has
support for drawing with tablet input. Since it is a vector graphics
program, I would expect it to give you the bezier curves that you want.
You can also set the snapping behavior to "snap to objects". Requires X
windows. Open source.

For Mac and PC there is also the commercial Adobe Illustrator which will
do what you want. CorelDraw would be another alternative.

I have a cheap commercial one (Lineform) which may be OK - I'm not
clear whether it is just my lack of experience with a tablet which is
making it hard - but I will look into Illustrator as well.

Thanks
