+/** \page visual_formula_editing Visual Formula Editing
+ * A visual formula editor allows users to easily edit formulas without having to learn and
+ * use complicated commands. A visual formula editor is a WYSIWYG editor. For OpenOffice Math
+ * this essentially means that you can click on the formula image, to get a caret, which you
+ * can move with arrow keys, and use to modify the formula by entering text, clicking buttons
+ * or using shortcuts.
+ *
+ * \subsection formula_trees Formula Trees
+ * A formula in OpenOffice Math is a tree of nodes, take for instance the formula
+ * "A + {B cdot C} over D", it looks like this
+ * \f$ \mbox{A} + \frac{\mbox{B} \cdot \mbox{C}}{\mbox{D}} \f$. The tree for this formula
+ * looks like this:
+ *
+ * \dot
+ * digraph {
+ * labelloc = "t";
+ * label= "Equation: \"A  + {B  cdot C} over D\"";
+ * size = "9,9";
+ * n0 [label="SmTableNode (1)"];
+ * n0 -> n1 [label="0"];
+ * n1 [label="SmLineNode (2)"];
+ * n1 -> n2 [label="0"];
+ * n2 [label="SmExpressionNode (3)"];
+ * n2 -> n3 [label="0"];
+ * n3 [label="SmBinHorNode (4)"];
+ * n3 -> n4 [label="0"];
+ * n4 [label="SmTextNode: A (5)"];
+ * n3 -> n5 [label="1"];
+ * n5 [label="SmMathSymbolNode: + (6)"];
+ * n3 -> n6 [label="2"];
+ * n6 [label="SmBinVerNode (7)"];
+ * n6 -> n7 [label="0"];
+ * n7 [label="SmExpressionNode (8)"];
+ * n7 -> n8 [label="0"];
+ * n8 [label="SmBinHorNode (9)"];
+ * n8 -> n9 [label="0"];
+ * n9 [label="SmTextNode: B (10)"];
+ * n8 -> n10 [label="1"];
+ * n10 [label="SmMathSymbolNode: &#183; (11)"];
+ * n8 -> n11 [label="2"];
+ * n11 [label="SmTextNode: C (12)"];
+ * n6 -> n12 [label="1"];
+ * n12 [label="SmRectangleNode (13)"];
+ * n6 -> n13 [label="2"];
+ * n13 [label="SmTextNode: D (14)"];
+ * }
+ * \enddot
+ *
+ * The vertices are nodes, their label says what kind of node and the number in parentheses is
+ *  the identifier of the node (In practices a pointer is used instead of the id). The direction
+ *  of the edges tells which node is parent and which is child. The label of the edges are the
+ *  child node index number, given to SmNode::GetSubNode() of the parent to get the child node.
+ *
+ *
+ * \subsection visual_lines Visual Lines
+ *
+ * Inorder to do caret movement in visual lines, we need a definition of caret position and
+ * visual line. In a tree such as the above there are three visual lines. There's the outer most
+ * line, with entries such as
+ * \f$\mbox{A}\f$, \f$ + \f$ and \f$ \frac{\mbox{B} \cdot \mbox{C}}{\mbox{D}} \f$. Then there's
+ *  the numerator line of the fraction it has entries \f$ \mbox{B} \f$, \f$ \cdot \f$ and \f$ \mbox{C} \f$.
+ *  And last by not least there's the denominator line of the fraction it's only entry is \f$ \mbox{D} \f$.
+ *
+ * For visual editing it should be possible to place a caret on both sides of any line entry,
+ * consider a line entry a character or construction that in a line is treated as a character.
+ *  Imagine the caret is placed to the right of the plus sign (id: 6), now if user presses
+ * backspace this should delete the plus sign (id: 6), and if the user presses delete this
+ * should delete the entire fraction (id: 7). This is because the caret is in the outer most
+ * line where the fraction is considered a line entry.
+ *
+ * However, inorder to prevent users from accidentally deleting large subtrees, just because
+ * they logically placed there caret a in the wrong line, require that complex constructions
+ * such as a fraction is selected before it is deleted. Thus in this case it wouldn't be
+ * deleted, but only selected and then deleted if the user hit delete again. Anyway, this is
+ * slightly off topic for now.
+ *
+ * Important about visual lines is that they don't always have an SmExpressionNode as root
+ * and the entries in a visual line is all the nodes of a subtree ordered left to right that
+ *  isn't either an SmExpressionNode, SmBinHorNode or SmUnHorNode.
+ *
+ *
+ * \subsection caret_positions Caret Positions
+ *
+ * A caret position in OpenOffice Math is represented by an instance of SmCaretPos.
+ * That is a caret position is a node and an index related to this node. For most nodes the
+ * index 0, means caret is in front of this node, the index 1 means caret is after this node.
+ * For SmTextNode the index is the caret position after the specified number of characters,
+ * imagine an SmTextNode with the number 1337. The index 3 in such SmTextNode would mean a
+ * caret placed right before 7, e.g. "133|7".
+ *
+ * For SmExpressionNode, SmBinHorNode and SmUnHorNode the only legal index is 0, which means
+ * in front of the node. Actually the index 0 may only because for the first caret position
+ * in a visual line. From the example above, consider the following subtree that constitutes
+ * a visual line:
+ *
+ * \dot
+ * digraph {
+ * labelloc = "t";
+ * label= "Subtree that constitutes a visual line";
+ * size = "7,5";
+ * n7 [label="SmExpressionNode (8)"];
+ * n7 -> n8 [label="0"];
+ * n8 [label="SmBinHorNode (9)"];
+ * n8 -> n9 [label="0"];
+ * n9 [label="SmTextNode: B (10)"];
+ * n8 -> n10 [label="1"];
+ * n10 [label="SmMathSymbolNode: &#183; (11)"];
+ * n8 -> n11 [label="2"];
+ * n11 [label="SmTextNode: C (12)"];
+ * }
+ * \enddot
+ * Here the caret positions are:
+ *
+ * <TABLE>
+ * <TR><TD><B>Caret position:</B></TD><TD><B>Example:</B></TD>
+ * </TR><TR>
+ *     <TD>{id: 8, index: 0}</TD>
+ *     <TD>\f$ \mid \mbox{C} \cdot \mbox{C} \f$</TD>
+ * </TR><TR>
+ *     <TD>{id: 10, index: 1}</TD>
+ *     <TD>\f$ \mbox{C} \mid \cdot \mbox{C} \f$</TD>
+ * </TR><TR>
+ *     <TD>{id: 11, index: 1}</TD>
+ *     <TD>\f$ \mbox{C} \cdot \mid \mbox{C} \f$</TD>
+ * </TR><TR>
+ *     <TD>{id: 12, index: 1}</TD>
+ *     <TD>\f$ \mbox{C} \cdot \mbox{C} \mid \f$</TD>
+ * </TR><TR>
+ * </TABLE>
+ *
+ * Where \f$ \mid \f$ is used to denote caret position.
+ *
+ * With these exceptions included in the definition the id and index: {id: 11, index: 0} does
+ * \b not constitute a caret position in the given context. Note the method
+ * SmCaretPos::IsValid() does not check if this invariant holds true, but code in SmCaret,
+ * SmSetSelectionVisitor and other places depends on this invariant to hold.
+ *
+ *
+ * \subsection caret_movement Caret Movement
+ *
+ * As the placement of caret positions depends very much on the context within which a node
+ * appears it is not trivial to find all caret positions and determine which follows which.
+ * In OpenOffice Math this is done by the SmCaretPosGraphBuildingVisitor. This visitor builds
+ * graph (an instance of SmCaretPosGraph) over the caret positions. For details on how this
+ * graph is build, and how new methods should be implemented see SmCaretPosGraphBuildingVisitor.
+ *
+ * The result of the SmCaretPosGraphBuildingVisitor is a graph over the caret positions in a
+ * formula, represented by an instance of SmCaretPosGraph. Each entry (instances of SmCaretPosGraphEntry)
+ * has a pointer to the entry to the left and right of itself. This way we can easily find
+ * the caret position to a right or left of a given caret position. Note each caret position
+ * only appears once in this graph.
+ *
+ * When searching for a caret position after a left click on the formula this map is also used.
+ * We simply iterate over all entries, uses the SmCaretPos2LineVisitor to find a line for each
+ * caret position. Then the distance from the click to the line is computed and we choose the
+ * caret position closest to the click.
+ *
+ * For up and down movement, we also iterator over all caret positions and use SmCaretPos2LineVisitor
+ * to find a line for each caret position. Then we compute the distance from the current
+ * caret position to every other caret position and chooses the one closest that is either
+ * above or below the current caret position, depending on whether we're doing up or down movement.
+ *
+ * This result of this approach to caret movement is that we have logically predictable
+ * movement for left and right, whilst leftclick, up and down movement depends on the sizes
+ * and placement of all node and may be less logically predictable. This solution also means
+ * that we only have one complex visitor generating the graph, imagine the nightmare if we
+ * had a visitor for movement in each direction.
+ *
+ * Making up and down movement independent of node sizes and placement wouldn't necessarily
+ * be a good thing either. Consider the formula \f$ \frac{1+2+3+4+5}{6} \f$, if the caret is
+ * placed as displayed here: \f$ \frac{1+2+3+4+5}{6 \mid} \f$, up movement should move to right
+ * after "3": \f$ \frac{1+2+3|+4+5}{6} \f$. However, such a move depends on the sizes and placement
+ * of all nodes in the fraction.

+Visual Formula Editor for LibreOffice Math
+==========================================
+
+This file contains a list of things to do for the visual formula editor.
+The visual formula editor hack was started by Jonas during GSoC...
+He is, as of writing this, still working on this features, but do by all
+means feel free to help out.
+
+Here is the list of things to be done. They are organized by complexity and necessity, note that
+some of the items are wishful thinking... If you have questions please feel free to ping me (Jonas)
+on IRC (jopsen) or e-mail me at jopsen@gmail.com.
+
+Easy
+----
+1. SmGraphicWidget::KeyInput relies on comparison of char, a better way must be available for CTRL+c
+2. Code style (missing spaces, linebreaks and a few renames)
+3. More documentation
+4. Extend NodeToTextVisitor to update token offsets so SmNode::GetRow and SmNode::GetColumn will work.
+   (These methods can be used to enable synchronization of caret positions between visual and non-visual editor).
+
+Medium
+------
+1. SmCursor::InsertCol() method for added columns to matrices should be implemented.
+2. SmCursor` should support deletion of lines, rows, cols and sub-/superscripts.
+3. SmCursor::InsertSubSup() should wrap the body in a SmBraceNode if the body is an SmOperNode, SmBinVerNode, etc.
+4. When OpenOffice Math runs in standalone mode it centers the current formula, this is not nice for visual editing.
+
+Complex
+-------
+1. SmAlignNode and SmFontNode are ignored by visual editor, figure out how these should work.
+2. Solve the flickering issue when drawing formulas (See dev@gsl.OpenOffice.org)
+3. Make " a shortcut for creating an SmTextNode with FNT_TEXT, also check that SmNodeToTextVisitor supports this.
+4. parse.cxx merges multiple blanks into one SmBlankNode, the visual editor doesn't...
+
+Complex and non-essential
+-------------------------
+* Global clipboard integration
+* Consider improving GUI for "Formula Elements"-dialog, most buttons work with visual editor
+* Consider allowing users to enter commands in visual editor, by prefixing the command...
+* Optimize things, for instance SmCursor::AnnotateSelection() is called way too many places...
+* Improve handling of MoveUp and MoveDown in SmCursor::Move, SmCaretPos2LineVisitor might need improvement.
+* Synchronized command text caret and visual editor caret.
