* Notes:
* "Active" means different things in Mac and Tk terminology --
* On Aqua, widgets are "Active" if they belong to the foreground window,
* "Inactive" if they are in a background window.
* Tk uses the term "active" to mean that the mouse cursor
* is over a widget; aka "hover", "prelight", or "hot-tracked".
* Aqua doesn't use this kind of feedback.
*
* The QuickDraw/Carbon coordinate system is relative to the
* top-level window, not to the Tk_Window. BoxToRect()
* accounts for this.

/*
* Apple XHIG Tab View Specifications:
*
* Control sizes: Tab views are available in regular, small, and mini sizes.
* The tab height is fixed for each size, but you control the size of the pane
* area. The tab heights for each size are listed below:
* - Regular size: 20 pixels.
* - Small: 17 pixels.
* - Mini: 15 pixels.
*
* Label spacing and fonts: The tab labels should be in a font that’s
* proportional to the size of the tab view control. In addition, the label
* should be placed so that there are equal margins of space before and after
* it. The guidelines below provide the specifications you should use for tab
* labels:
* - Regular size: System font. Center in tab, leaving 12 pixels on each side.
* - Small: Small system font. Center in tab, leaving 10 pixels on each side.
* - Mini: Mini system font. Center in tab, leaving 8 pixels on each side.
*
* Control spacing: Whether you decide to inset a tab view in a window or
* extend its edges to the window sides and bottom, you should place the top
* edge of the tab view 12 or 14 pixels below the bottom edge of the title bar
* (or toolbar, if there is one). If you choose to inset a tab view in a
* window, you should leave a margin of 20 pixels between the sides and bottom
* of the tab view and the sides and bottom of the window (although 16 pixels
* is also an acceptable margin-width). If you need to provide controls below
* the tab view, leave enough space below the tab view so the controls are 20
* pixels above the bottom edge of the window and 12 pixels between the tab
* view and the controls.
* If you choose to extend the tab view sides and bottom so that they meet the
* window sides and bottom, you should leave a margin of at least 20 pixels
* between the content in the tab view and the tab-view edges.
