- Make the various virtual methods of GimpPaintCore use a list of drawables as argument instead of a single drawable. - gimp_brush_core_eval_transform_dynamics() can work with an image as argument rather than a drawable as it doesn't actually depends on specific drawable data. - New function gimp_paint_tool_enable_multi_paint() to be used in init() method of paint tools to announce that this tool can work with multiple layers selected. - Use gimp_paint_tool_enable_multi_paint() in the GimpSourceTool base class only for now. This is a first step for multi-layer drawing, but we don't want it to be possible in just any random cases, which is why I add a special function to advertize this capability. We will use it for special-casing the clone (as well as heal and perspective tools most likely) tool to work on several layers at once. At this step, it is still very bugged and not really working properly. In particular, since we don't process the drawable offset early anymore (because it makes no sense when we pass a list of drawables with different offsets), I suspect that all the offset-related code will be very broken.
