+/**
+ * This class maintains a snapshot of an instance of {@link ITerminalTextData}.
+ * While the {@link ITerminalTextData} continues changing, the snapshot remains
+ * unchanged until the next snapshot is taken by calling
+ * {@link #updateSnapshot(boolean)}. This is important, because the
+ * {@link ITerminalTextData} might get modified by another thread. Suppose you
+ * would want to draw the content of the {@link ITerminalTextData} using the
+ * following loop:
+ *
+ *
+ * for (int line = 0; line < term.getHeight(); line++)
+ * for (int column = 0; column < term.getWidth(); column++)
+ * drawCharacter(column, line, term.getChar(column, line), term.getStyle(column, line));
+ *
+ *
+ * This might fail because the background thread could change the dimensions of
+ * the {@link ITerminalTextData} while you iterate the loop. One solution would
+ * be to put a synchronized(term){} statement around the code. This
+ * has two problems: 1. you would have to know about the internals of the
+ * synchronisation of {@link ITerminalTextData}. 2. The other thread that
+ * changes {@link ITerminalTextData} is blocked while the potentially slow
+ * drawing is done.
+ *
+ * Solution: Take a snapshot of the terminal and use the snapshot to draw
+ * the content. There is no danger that the data structure get changed while you
+ * draw. There are also methods to find out what has changed to minimize the
+ * number of lines that get redrawn.
+ *
+ *
+ *
+ * Drawing optimization: To optimize redrawing of changed lines, this
+ * class keeps track of lines that have changed since the previous snapshot.
+ *
+ *
+ *
+ * // iterate over the potentially changed lines
+ * for (int line = snap.getFirstChangedLine(); line <= snap.getLastChangedLine(); line++)
+ * // redraw only if the line has changed
+ * if (snap.hasLineChanged(line))
+ * for (int column = 0; column < snap.getWidth(); column++)
+ * drawCharacter(column, line, snap.getChar(column, line), snap.getStyle(column, line));
+ *
+ *
+ *
+ * Scroll optimization: Often new lines are appended at the bottom of the
+ * terminal and the rest of the lines are scrolled up. In this case all lines
+ * would be marked as changed. To optimize for this case,
+ * {@link #updateSnapshot(boolean)} can be called with true for the
+ * detectScrolling parameter. The object will keep track of
+ * scrolling. The UI must first handle the scrolling and then use the
+ * {@link #hasLineChanged(int)} method to determine scrolling:
+ *
+ *
+ * // scroll the visible region of the UI <b>before</b> drawing the changed lines.
+ * doUIScrolling(snap.getScrollChangeY(), snap.getScrollChangeN(), snap.getScrollChangeShift());
+ * // iterate over the potentially changed lines
+ * for (int line = snap.getFirstChangedLine(); line <= snap.getFirstChangedLine(); line++)
+ * // redraw only if the line has changed
+ * if (snap.hasLineChanged(line))
+ * for (int column = 0; column < snap.getWidth(); column++)
+ * drawCharacter(column, line, snap.getChar(column, line), snap.getStyle(column, line));
+ *
+ *
+ *
+ *
+ * Threading Note: This class is not thread safe! All methods have to be
+ * called by the a same thread, that created the instance by calling
+ * {@link ITerminalTextDataReadOnly#makeSnapshot()}.
