Oh, thats is problematic, X does not provide ways to resize/rotate/etc
pixmaps, so to acomplish it you need a way to resize pixmap by your
own. Algorithmically in emacs lisp it is not a problem for small
pixmaps(e.g 4x4 pixels), but for larger pixmaps you need full featured
algorithms, such as bicubic interpolation or other. When i was
playing with pixmaps i've played with bicubic interpolation a little
(you can find it at the end of xlib-xpm.el file), but then i realized
that is too much effort for the argueable feature ..
So, no what you want is not possible with xwem, however if you will
find an external library that has function which is passed with two
arguments - Pixmaps and resamples first pixmap to the size of second
pixmap - xwem can use it via FFI ..
