cool :) applied (in CVS)

the current behaviour is that window resizes don't affect the zoom level,
unless exactly the entire file is being displayed and you're widening
the window. Check out sample-display.c:sample_display_init_display().
Let me know if anything different is happening though!

is this behaviour ok? I wanted to make it intuitive (so you can just "make
the whole thing bigger" if you want) -- perhaps it should just stick to one
mode of resizing all the time [and this could be a user option, like in
the gimp]?

no; and there's no need to register changes of zoom. you only need to
register an operation when you modify the contents of a sounddata, ie.
the sampling format, length, selections or sample data.

(I've updated the plugin writer's guide in CVS to clarify this.)
