Changes: Clear the pixmap cache when the window is not shown on the display anymore or has been minimized.
RevBy: Armin Berres
Details: Widgets like MScalableImage and MLabel (when showing rich-texts) use QPixmapCache for the caching of pixmaps. If the window gets invisible or has been minimized there is no need to keep the pixmaps in the cache.
