Hello,

I'm trying to make image from biological data. I have some sequence of
characters and alignment information where some other sequence match.
I want to present all of these matches in image where I could select
some match and present the information.

So the question is, what package should I use? I have been trying to
use GWTCanvas but is there some other package? My problem with
GWTCanvas is that the pixels and coordinates get messed up. I did read
about it but I'm probably missing something.

The idea is to build Google maps kind of tool but with just few
functions. Some zooming and moving the image and selecting individual
lines or selecting all lines that intersect some interval. And maybe
some mouse over stuff. I managed to launch some handlers using
GWTCanvas so that should not be the problem if that is the right
package for this.

All ideas and tips are welcome, I'm not completely sure that the path
I have choose is right. :) I will post some code later...
