[KLUG Members] (Inkscape) Stumped at the beginning

[Adam Tauno Williams]

Ok, I have to make an icon/logo - and it seems Inkscape is the place to
do this as it can then be resized like a maniac.  But if I make a logo
in Inkscape, and something like a letter sized canvas, what is the
procedure to go about using this in other, non-svg images.  For instance
I'd have to embed to logo in a pair of gifs: on 173x156 and another
182x30 (the size and format are not for my choosing).  Can I paste an
SVG image into a GIMP canvas and resize it?  I'm ignorant enough to not
really be able to feel how to approach this kind of problem.
