/*************************************************************
 * gtk_style_attach:
 *     Attach a style to a window; this process allocates the
 *     colors and creates the GC's for the style - it specializes
 *     it to a particular visual and colormap. The process
 *     may involve the creation of a new style if the style
 *     has already been attached to a window with a different
 *     style and colormap.
 *   arguments:
 *     style:
 *     window: 
 *   results:
 *     Either the style parameter, or a newly created style.
 *     If the style is newly created, the style parameter
 *     will be dereferenced, and the new style will have
 *     a reference count belonging to the caller.
 *
 * FIXME: The sequence - 
 *    create a style => s1
 *    attach s1 to v1, c1 => s1
 *    attach s1 to v2, c2 => s2
 *    detach s1 from v1, c1
 *    attach s1 to v2, c2 => s3
 * results in two separate, unlinked styles s2 and s3 which
 * are identical and could be shared. To fix this, we would
 * want to never remove a style from the list of linked
 * styles as long as as it has a reference count. However, the 
 * disadvantage of doing it this way means that we would need two 
 * passes through the linked list when attaching (one to check for 
 * matching styles, one to look for empty unattached styles - but 
 * it will almost never be longer than 2 elements.
