Hombre 4665b88788 Modified Preview Canvas 
- Now the Preview can show free space around the image (the image's
corner will coincide with the center of the preview area)
- Editing objects can now be manipulated in this free space
- The editing mechanism has been split : it was completely handled in
rtengine before, now rtengine still handle the pipette's data provider,
but rtgui now handle the objects data provider.
- Bugfix: when using coarse rotate in the Editor panel, the Gradient
widgets are now correctly displayed

/** @file
*
* The Edit mechanism is designed to let tools (subscribers) communicate with the preview area (provider).
* Subscribers will be tools that need to create some graphics in the preview area, to let the user interact
* with it in a more user friendly way.
*
* Do not confuse with _local_ editing, which is another topic implemented in another class. The Edit feature
* is also not supported in batch editing from the File Browser.
*
* Edit tool can be of 2 types: pipette editing and object editing.
*
* ## Pipette edition
*
* By using this class, a pipette mechanism can be handled on the preview.
*
* Each pipette Edit tool must have a unique ID, that will identify them, and which let the ImProcCoordinator
* or other mechanism act as appropriated. They are all defined in rtgui/editid.h. A buffer type has to be given
* too, to know which kind of buffer to allocate (see EditSubscriber::BufferType).
*
* Only the first mouse button can be used to manipulate the pipette on the Preview, that's why the developer has
* to implement at least the following 4 methods:
* - mouseOver
* - button1Pressed
* - drag1
* - button1Released
*
* Actually, only curves does use this class, and everything is handled for curve implementor (as much as possible).
* See the curve's class documentation to see how to implement the curve's pipette feature.
*
* ### Event handling
*
* The mouseOver method is called on each mouse movement, excepted when dragging a point. This method can then access
* the pipetteVal array values, which contain the mean of the pixel read in the buffer, or -1 of the cursor is outside
* of the image. In this case, EditDataProvider::object is also set to 0 (and 1 if over the image).
*
* When the user will click on the left mouse button while pressing the CTRL key, the button1Pressed will be called.
* Setting "dragging" to true (or false) is not required for the pipette type editing.
*
* The drag1 method will be called on all subsequent mouse move. The pipetteVal[3] array will already be filled with
* the mean of the read values under the cursor (actually a fixed square of 8px). If the BufferType is BT_SINGLEPLANE_FLOAT,
* only the first array value will be filled.
*
* Then the button1Released will be called to stop the dragging.
*
* ## Object edition
*
* By using this class, objects can be drawn and manipulated on the preview.
*
* The developer has to handle the buttonPress, buttonRelease, drag and mouseOver method that he needs. There
* are buttonPress, buttonRelease and drag methods dedicated to each mouse button, for better flexibility
* (e.g.button2Press, button2Release, drag2 will handle event when mouse button 2 is used first). RT actually
* does not handle multiple mouse button event (e.g. button1 + button2), only one at a time. The first button pressed
* set the mechanism, all other combined button press are ignored.
*
* The developer also have to fill 2 display list with object of the Geometry subclass. Each geometric shape
* _can_ be used in one or the other, or both list at a time.
*
* The first list (visibleGeometry) is used to be displayed on the preview. The developer will have to set their state
* manually (see Geometry::State), but the display shape, line width and color can be handled automatically, or with
* specific values. To be displayed, the F_VISIBLE flag has to be set through the setActive or setVisible methods.
*
* The second list (mouseOverGeometry) is used in a backbuffer, the color used to draw the shape being the id of the
* mouseOverGeometry. As an example, you could use a circle line to represent the line to the user, but use another
* Circle object, filled, to be used as mouseOver detection. The association between both shape (visible and mouseOver)
* is handled by the developer. To be displayed on this backbuffer, the F_HOVERABLE flag has to be set through the
* setActive or setHoverable methods.
*
*
* ### Event handling
*
* RT will draw in the back buffer all mouseOverGeometry set by the developer once the Edit button is pressed, and handle
* the events automatically.
*
* RT will call the mouseOver method on each mouse movement where no mouse button is pressed.
*
* On mouse button press over a mouseOverGeometry, it will call the button press method corresponding to the button
* (e.g. button1Pressed for mouse button 1), with the modifier key as parameter. Any other mouse button pressed at
* the same time will be ignored. It's up to the developer to decide whether it leads to a drag movement or not,
* by setting the "dragging" boolean to true.
*
* In this case, RT will then sent drag1 event (to stay with our button 1 pressed example) on each mouse movement. It's up
* to the developer of the tool to handle the dragging. The EditProvider class will help you in this by handling the actual
* position in various coordinate system and ways.
*
* When the user will release the mouse button, RT will call the button1Release event (in our example). The developer have
* then to set the "dragging" flag to false.
*
* Each of these methods have to returns a boolean value saying that the preview has to be refreshed or not (i.e. the displayed
* geometry).
*
* ## Other general internal implementation notes
*
* When a tool is being constructed, unique IDs are affected to the EditSubscribers of the Pipette type.
* Then the EditorPanel class will ask all ToolPanel to register the 'after' preview ImageArea object as data provider.
* The Subscribers have now to provide a toggle button to click on to start the Edit listening. When toggling on, the Subscriber
* register itself to the DataProvider, then an event is thrown through the standard ToolPanelListener::panelChanged
* method to update the preview with new graphics to be displayed. If a previous Edit button was active, it will be deactivated
* (the Edit buttons are mutually exclusive). For the Pipette type, a buffer will be created and has to be populated
* by the developer in rtengine's pipeline. The unique pipette ID will be used to know where to fill the buffer, as each pipette
* will need different data, corresponding to the state of the image right before the tool that needs pipette values. E.g for
* the HSV tool, the Hue and Saturation and Value curves are applied on the current state of the image. That's why the pipette
* of the H, S and V curve will share the same data of this "current state", otherwise the read value would be wrong.
*
* When the mouse button 1 is pressed while pressing the CTRL key, the button1Pressed method will be called.
*
* When the Edit process stops, the Subscriber is removed from the DataProvider, so buffers can be freed up.
* A new ToolPanelListener::panelChanged event is also thrown to update the preview again, without the tool's
* graphical objects. The Edit button is also toggled off (by the user or programmatically).
*
* It means that each Edit buttons toggled on will start an update of the preview which might or might not create
* a new History entry, depending on the ProcEvent used.
