Bug 668016 - Accidentally clicking ruler loses active tool's state Add two new tools, GimpGuideTool and GimpSamplePointTool. They are one-trick-ponies and can only create new or move existing guides and sample points. They can't be selected from the toolbox, only temporarily pushed as active tools on top of any active tool using their public start() APIs. Use that API to enable them when the rulers are clicked, and replace the entire guide and sample point moving code in GimpMoveTool and GimpColorTool by simple calls to that API. This might look like overkill but can easily be used for other features like moving guides from within the paint tools (mirror painting) or gegl filters (preview curtain).

app: allow moving an intersecting pair of guides with the Move tool This commit adds support for moving together an intersecting pair of guides using the Move tool, by dragging the guides at their point of intersection. This is useful when the guides are used to mark a point, rather than a pair of lines (e.g., as is the case for the mandala symmetry guides, which mark the symmetry's point of origin). Add gimp_image_pick_guides(), which can return a set of guides, rather than a single guide. The API allows an arbitrary set of guides to be returned, but, in practice, at most two intersecting guides are returned, as per the above. In GimpMoveTool and GimpGuideTool, add support for moving multiple guides together, and, in GimpMoveTool, use gimp_image_pick_guides() to potentially pick multiple guides.
