Jehan 3038c751bc app, pdb: use the real theme background color for brushes with GIMP_VIEW_BG_USE_STYLE.
Previous code was using the correct background color from the theme, but
the foreground color was always either white or black (depending on GUI
config color scheme). Instead, just use the foreground color from theme.

Since core/ doesn't have access to GTK, hence the theme, we had to
update GimpViewable's get_preview() and get_pixbuf() abstract methods to
have a color argument for recoloring previews (when relevant, which for
most types of viewables is not).
