or there used to be, I do not remember it's name exactly, but it was the plugin version of Gertrudis Pro. I think everybody combines using different editing programs on one photo, I know I have many time done a photo in Gertrudis, then open it in photoshop or twistedbrush, You might take a look at PD Pro, I think it is free, but do not remember, but Gertrudis is based on this editing program and it is a pretty nice program also.
