- * widget hierarchy). Wildcard elements are handled separately from
- * "exact" elements because once they appear at a particular level in
- * the stack they remain active for all deeper levels; exact elements
- * are only relevant at a particular level. For example, when searching
- * for options relevant in a particular window, the entire wildcard
- * stacks get checked, but only the portions of the exact stacks that
- * pertain to the window's parent. Lastly, name and class stacks are
- * kept separate because different search keys are used when searching
- * them; keeping them separate speeds up the searches.
+ * there are eight additional structures called "stacks", which are used to
+ * speed up queries into the option database. The stack structures are
+ * designed for the situation where an individual widget makes repeated
+ * requests for its particular options. The requests differ only in their last
+ * name/class, so during the first request we extract all the options
+ * pertaining to the particular widget and save them in a stack-like cache;
+ * subsequent requests for the same widget can search the cache relatively
+ * quickly. In fact, the cache is a hierarchical one, storing a list of
+ * relevant options for this widget and all of its ancestors up to the
+ * application root; hence the name "stack".
+ *
+ * Each of the eight stacks consists of an array of Elements, ordered in terms
+ * of levels in the window hierarchy. All the elements relevant for the
+ * top-level widget appear first in the array, followed by all those from the
+ * next-level widget on the path to the current widget, etc. down to those for
+ * the current widget.
+ *
+ * Cached information is divided into eight stacks according to the CLASS,
+ * NODE, and WILDCARD flags. Leaf and non-leaf information is kept separate to
+ * speed up individual probes (non-leaf information is only relevant when
+ * building the stacks, but isn't relevant when making probes; similarly, only
+ * non-leaf information is relevant when the stacks are being extended to the
+ * next widget down in the widget hierarchy). Wildcard elements are handled
+ * separately from "exact" elements because once they appear at a particular
+ * level in the stack they remain active for all deeper levels; exact elements
+ * are only relevant at a particular level. For example, when searching for
+ * options relevant in a particular window, the entire wildcard stacks get
+ * checked, but only the portions of the exact stacks that pertain to the
+ * window's parent. Lastly, name and class stacks are kept separate because

+ * TkTextLines. Since Tk 8.5, with pixel line height calculations and peer
+ * widgets, this dummy line is becoming somewhat of a liability, and special
+ * case code has been required to deal with it. It is probably a good idea to
+ * investigate removing the dummy line completely. This could result in an
+ * overall simplification (although it would require new special case code to
+ * deal with the fact that '.text index end' would then not really point to a
+ * valid line, rather it would point to the beginning of a non-existent line
+ * one beyond all current lines - we could perhaps define that as a

+ * "Calculations of line pixel heights and the size of the vertical
+ * scrollbar."
+ *
+ * Given that tag, font and elide changes can happen to large numbers of
+ * diverse chunks in a text widget containing megabytes of text, it is not
+ * possible to recalculate all affected height information immediately any
+ * such change takes place and maintain a responsive user-experience. Yet, for
+ * an accurate vertical scrollbar to be drawn, we must know the total number
+ * of vertical pixels shown on display versus the number available to be
+ * displayed.
+ *
+ * The way the text widget solves this problem is by maintaining cached line
+ * pixel heights (in the BTree for each logical line), and having asynchronous
+ * timer callbacks (i) to iterate through the logical lines recalculating
+ * their heights, and (ii) to recalculate the vertical scrollbar's position
+ * and size.
+ *
+ * Typically this works well but there are some situations where the overall
+ * functional design of this file causes some problems. These problems can
+ * only arise because the calculations used to display lines on screen are not
+ * connected to those in the iterating-line- recalculation-process.
+ *
+ * The reason for this disconnect is that the display calculations operate in
+ * display lines, and the iteration and cache operates in logical lines.
+ * Given that the display calculations both need not contain complete logical
+ * lines (at top or bottom of display), and that they do not actually keep
+ * track of logical lines (for simplicity of code and historical design), this
+ * means a line may be known and drawn with a different pixel height to that
+ * which is cached in the BTree, and this might cause some temporary
+ * undesirable mismatch between display and the vertical scrollbar.
+ *
+ * All such mismatches should be temporary, however, since the asynchronous
+ * height calculations will always catch up eventually.
+ *
+ * For further details see the comments before and within the following
+ * functions below: LayoutDLine, AsyncUpdateLineMetrics, GetYView,
+ * GetYPixelCount, TkTextUpdateOneLine, TkTextUpdateLineMetrics.
+ *
+ * For details of the way in which the BTree keeps track of pixel heights, see
+ * tkTextBTree.c. Basically the BTree maintains two pieces of information: the
+ * logical line indices and the pixel height cache.

+ * TK_LAYOUT_WITH_BASE_CHUNKS:
+ *
+ * With this macro set, collect all char chunks that have no holes
+ * between them, that are on the same line and use the same font and font
+ * size. Allocate the chars of all these chunks, the so-called "stretch",
+ * in a DString in the first chunk, the so-called "base chunk". Use the
+ * base chunk string for measuring and drawing, so that these actions are
+ * always performed with maximum context.
+ *
+ * This is necessary for text rendering engines that provide ligatures
+ * and sub-pixel layout, like ATSU on Mac. If we don't do this, the
+ * measuring will change all the time, leading to an ugly "tremble and
+ * shiver" effect. This is because of the continuous splitting and
+ * re-merging of chunks that goes on in a text widget, when the cursor or
+ * the selection move.
+ *
+ * Side effects:
+ *
+ * Memory management changes. Instead of attaching the character data to
+ * the clientData structures of the char chunks, an additional DString is
+ * used. The collection process will even lead to resizing this DString
+ * for large stretches (> TCL_DSTRING_STATIC_SIZE == 200). We could
+ * reduce the overall memory footprint by copying the result to a plain
+ * char array after the line breaking process, but that would complicate
+ * the code and make performance even worse speedwise. See also TODOs.
+ *
+ * TODOs:
+ *
+ * - Move the character collection process from the LayoutProc into
+ * LayoutDLine(), so that the collection can be done before actual
+ * layout. In this way measuring can look at the following text, too,
+ * right from the beginning. Memory handling can also be improved with
+ * this. Problem: We don't easily know which chunks are adjacent until
+ * all the other chunks have calculated their width. Apparently marks
+ * would return width==0. A separate char collection loop would have to
+ * know these things.
+ *
+ * - Use a new context parameter to pass the context from LayoutDLine() to
+ * the LayoutProc instead of using a global variable like now. Not
+ * pressing until the previous point gets implemented.

+ * Theme engine resource cache.
+ *
+ * Copyright (c) 2004, Joe English
+ *
+ * The problem:
+ *
+ * Tk maintains reference counts for fonts, colors, and images,
+ * and deallocates them when the reference count goes to zero.
+ * With the theme engine, resources are allocated right before
+ * drawing an element and released immediately after.
+ * This causes a severe performance penalty, and on PseudoColor
+ * visuals it causes colormap cycling as colormap entries are
+ * released and reused.
+ *
+ * Solution: Acquire fonts, colors, and objects from a
+ * resource cache instead of directly from Tk; the cache
+ * holds a semipermanent reference to the resource to keep
+ * it from being deallocated.
+ *
+ * The plumbing and control flow here is quite contorted;
+ * it would be better to address this problem in the core instead.
+ *
+ * @@@ BUGS/TODO: Need distinct caches for each combination
+ * of display, visual, and colormap.
+ *
+ * @@@ Colormap flashing on PseudoColor visuals is still possible,
+ * but this will be a transient effect.

+# CHANGES:
+# + Remove xxx_TCL_DECLARED #ifdeffery
+# + Use application-defined storage class specifier instead of "EXTERN"
+# + Add "epoch" and "revision" fields to stubs table record
+# + Remove dead code related to USE_*_STUB_PROCS (emitStubs, makeStub)
+# + Second argument to "declare" is used as a status guard
+# instead of a platform guard.
+# + Use void (*reserved$i)(void) = 0 instead of void *reserved$i = NULL
+# for unused stub entries, in case pointer-to-function and
+# pointer-to-object are different sizes.
+# + Allow trailing semicolon in function declarations
+# + stubs table is const-qualified

+ * +++ The Geometry Propagation Dance.
+ *
+ * When a slave window requests a new size or some other parameter changes,
+ * the manager recomputes the required size for the master window and calls
+ * Tk_GeometryRequest(). This is scheduled as an idle handler so multiple
+ * updates can be processed as a single batch.
+ *
+ * If all goes well, the master's manager will process the request
+ * (and so on up the chain to the toplevel window), and the master
+ * window will eventually receive a <Configure> event. At this point
+ * it recomputes the size and position of all slaves and places them.
+ *
+ * If all does not go well, however, the master's request may be ignored
+ * (typically because the top-level window has a fixed, user-specified size).
+ * Tk doesn't provide any notification when this happens; to account for this,
+ * we also schedule an idle handler to call the layout procedure
+ * after making a geometry request.
+ *
+ * +++ Slave removal <<NOTE-LOSTSLAVE>>.
+ *
+ * There are three conditions under which a slave is removed:
+ *
+ * (1) Another GM claims control
+ * (2) Manager voluntarily relinquishes control
+ * (3) Slave is destroyed
+ *
+ * In case (1), Tk calls the manager's lostSlaveProc.
+ * Case (2) is performed by calling Tk_ManageGeometry(slave,NULL,0);
+ * in this case Tk does _not_ call the LostSlaveProc (documented behavior).
+ * Tk doesn't handle case (3) either; to account for that we
+ * register an event handler on the slave widget to track <Destroy> events.

+ * Each pane carries two pieces of state: the request size and the
+ * position of the following sash. (The final pane has no sash,
+ * its sash position is used as a sentinel value).
+ *
+ * Pane geometry is determined by the sash positions.
+ * When resizing, sash positions are computed from the request sizes,
+ * the available space, and pane weights (see PlaceSashes()).
+ * This ensures continuous resize behavior (that is: changing
+ * the size by X pixels then changing the size by Y pixels
+ * gives the same result as changing the size by X+Y pixels
+ * in one step).
+ *
+ * The request size is initially set to the slave window's requested size.
+ * When the user drags a sash, each pane's request size is set to its
+ * actual size. This ensures that panes "stay put" on the next resize.
+ *
+ * If reqSize == 0, use 0 for the weight as well. This ensures that
+ * "collapsed" panes stay collapsed during a resize, regardless of
+ * their nominal -weight.

+ * Copyright 2004, Joe English

+ * Support routines for scrollable widgets.
+ *
+ * (This is sort of half-baked; needs some work)
+ *
+ * Scrollable interface:
+ *
+ * + 'first' is controlled by [xy]view widget command
+ * and other scrolling commands like 'see';
+ * + 'total' depends on widget contents;
+ * + 'last' depends on first, total, and widget size.
+ *
+ * Choreography (typical usage):
+ *
+ * 1. User adjusts scrollbar, scrollbar widget calls its -command
+ * 2. Scrollbar -command invokes the scrollee [xy]view widget method
+ * 3. TtkScrollviewCommand calls TtkScrollTo(), which updates
+ * 'first' and schedules a redisplay.
+ * 4. Once the scrollee knows 'total' and 'last' (typically in
+ * the LayoutProc), call TtkScrolled(h,first,last,total) to
+ * synchronize the scrollbar.
+ * 5. The scrollee -[xy]scrollcommand is called (in an idle callback)
+ * 6. Which calls the scrollbar 'set' method and redisplays the scrollbar.
+ *
+ * If the scrollee has internal scrolling (e.g., a 'see' method),
+ * it should TtkScrollTo() directly (step 2).
+ *
+ * If the widget value changes, it should call TtkScrolled() (step 4).
+ * (This usually happens automatically when the widget is redisplayed).
+ *
+ * If the scrollee's -[xy]scrollcommand changes, it should call
+ * TtkScrollbarUpdateRequired, which will invoke step (5) (@@@ Fix this)
