* app/layers_dialog.c: when computing a preview, limit the scale ratio
to a maximum of 1.0. By doing so we avoid to scale drawables up if the
image (canvas) size becomes larger than the drawable. Fixes bug #31098.

Added some controls to the nav window. Yep. I know that the
buttons are toooo biGGG.
Preview cache changes. Now prime preview cache with a image
so that later we have a better chance of a hit. Still
needs to be more intelligent at doing this (needs to pick largest
out of the cache & use its size as the size to prime with).

Added thumbnail image preview functions.
Previews are visible on the L&C&P dialogs as well as in the
drawables/channels/ menus generated for plugins
(see the bumpmap & Mapobject plugins).
PDB interface exists to simply extract a thumbnail preview
of a given size. This is much quicker & more efficient
than getting the image data tile-by-tile if you only need a small
image since a "preview cache" has been implemented. This cache also
reduces the number of times the tiles cached is scanned since smaller
previews are always generated from large ones if they exists and
are valid.
Some possible usages (I don't intend to implement these ideas. Just
suggestions). More plugins using the thumbnail preview (ie any that
use multiple images). Indication of "active image" somewhere.....
Actually almost anywhere a drawable/image name appears.
