70 *
71 * You may wish to begin by reading the

89 * CtkTextView has a main css node with name textview and style class .view,
90 * and subnodes for each of the border windows, and the main text area,
91 * with names border and text, respectively. The border nodes each get
92 * one of the style classes .left, .right, .top or .bottom.
93 *
94 * A node representing the selection will appear below the text node.
95 *
96 * If a context menu is opened, the window node will appear as a subnode
97 * of the main node.

101/* How scrolling, validation, exposes, etc. work.
102 *
103 * The expose_event handler has the invariant that the onscreen lines
104 * have been validated.
105 *
106 * There are two ways that onscreen lines can become invalid. The first
107 * is to change which lines are onscreen. This happens when the value
108 * of a scroll adjustment changes. So the code path begins in
109 * ctk_text_view_value_changed() and goes like this:
110 * - cdk_window_scroll() to reflect the new adjustment value
111 * - validate the lines that were moved onscreen
112 * - cdk_window_process_updates() to handle the exposes immediately
113 *
114 * The second way is that you get the “invalidated” signal from the layout,
115 * indicating that lines have become invalid. This code path begins in
116 * invalidated_handler() and goes like this:
117 * - install high-priority idle which does the rest of the steps
118 * - if a scroll is pending from scroll_to_mark(), do the scroll,
119 * jumping to the ctk_text_view_value_changed() code path
120 * - otherwise, validate the onscreen lines
121 * - DO NOT process updates
122 *
123 * In both cases, validating the onscreen lines can trigger a scroll
124 * due to maintaining the first_para on the top of the screen.
125 * If validation triggers a scroll, we jump to the top of the code path
126 * for value_changed, and bail out of the current code path.
127 *
128 * Also, in size_allocate, if we invalidate some lines from changing
129 * the layout width, we need to go ahead and run the high-priority idle,
130 * because CTK sends exposes right after doing the size allocates without
131 * returning to the main loop. This is also why the high-priority idle
132 * is at a higher priority than resizing.
133 *
