 /*
- * Quoth DrawThemeTab() reference manual:
- * "Small tabs have a height of 16 pixels large tabs have a height of
- * 21 pixels. (The widths of tabs are variable.) Additionally, the
- * distance that the tab overlaps the pane must be included in the tab
- * rectangle this overlap distance is always 3 pixels, although the
- * 3-pixel overlap is only drawn for the front tab."
+ * 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.
