// VkSetHighlightingPixmap utility

// Given an XPM pixmap that has the background field set

// will install the pixmap in a label or button in such a way
// that the pixmap will locate-highlight in the SGI-style.
// See bug warning below.
//
// Some variation of this code should migrate into ViewKit
// in a future release for easier use.
