// [TAG]  		EIP55548
// [Category]  	Improvement
// [Description]  	Support to display Multiple GIF and display other image
// format when Active animated Gif is displaying.
// [Files]  		dogif.c and dogifmgr.c

// [TAG]  		EIP53740
// [Category]  	Bug Fix
// [Severity]  	Normal
// [Symptom]  	Animation does not continue after the last frame of the
// logo.
// [RootCause]  	Animation is continued upto the last frame of the
// animated image
