      If a MNG file created in 'PNG MNG ConstructionSet' (http://www.mindworkshop.com/pngpro.html) contains a LOOP block (logo6.mng) and is used in a AnimatedImage QML, the resulting application will leak memory at the end of each loop iteration. If however, the MNG file uses the TERM block, which loops at the end of the iteration (see FiC_logo.mng), then the leak is avoided.
