Browse Source 
-Fixed cancelled MessageBox erroneously stating "Node not extracted" while using the Export Skin Icon tool.
-Skin icons can no longer be exported for skins with abnormal resolutions.
-Skin paper dolls can no longer be created for skins with abnormal resolutions. A default skin icon will be returned instead.
-Fix crash for skin textures smaller than the base resolution skin size
-Fix crash for boxes placed outside of the base resolution skin canvas
