Bug 735810 - performance shrinkage of Paths tool

Browse Source 
Use a GQueue instead of a GList in GimpCanvasGroup, so adding items
takes constant time instead of O(n). Also, removing items was
traversing the list twice. This should generally speed up tools with
lots of canvas items.

Also, add a private pointer to the instance struct instead of using a
GET_PRIVATE() macro.
