/**
 * A very simple pixmap cache for theme plugins. TQPixmapCache is not used
 * since it uses TQString keys which are not needed. All the information we
 * need can be encoded in a numeric key. Using TQIntCache instead allows us to
 * skip the string operations.
 *
 * This class is mostly just inline methods that do bit operations on a key
 * composed of the widget ID, width and/or height, and then calls
 * TQIntCache::tqfind().
 *
 * One other thing to note is that full, horizontal, and vertically scaled
 * pixmaps are not used interchangeably. For example, if you insert a fully
 * scaled pixmap that is 32x32 then request a horizontally scaled pixmap with
 * a width of 32, they will not match. This is because a pixmap that has been
 * inserted into the cache has already been scaled at some point and it is
 * very likely the vertical height was not originally 32. Thus the pixmap
 * will be wrong when drawn, even though the horizontal width matches.
