+ * Ttk 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.

+ * +++ 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.

+ *
+ * Pane geometry is determined by the sash positions.
+ * When resizing, sash positions are computed from the request sizes,

+ * This ensures continuous resize behavior (that is: changing

+ * 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

+ * 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. ScrollviewCommand calls ScrollTo(), which updates
+ * 'first' and schedules a redisplay.
+ * 4. Once the scrollee knows 'total' and 'last' (typically in
+ * the LayoutProc), call Scrolled(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 ScrollTo() directly (step 2).
+ *
+ * If the widget value changes, it should call Scrolled() (step 4).
+ * (This usually happens automatically when the widget is redisplayed).
+ *
+ * If the scrollee's -[xy]scrollcommand changes, it should call
+ * ScrollbarUpdateRequired, which will invoke step (5) (@@@ Fix this)
