+The class encapsulates:
+1. a pointer to a function which takes an argument of type TAny* and returns
+a TInt.
+2. a pointer which is passed to the function every time it is called.
+The pointer can point to any object. It can also be NULL.
+The callback function can be a static function of a class,
+e.g. TInt X::Foo(TAny *) or it can be a function which is not a member of
+any class, e.g. TInt Foo(TAny *).
+When used with the CIdle and the CPeriodic classes, the callback function
+is intended to be called repeatedly; the encapsulated pointer is passed on
+each call. Typically, the pointer refers to an object which records the state
+of the task across each call. When used with CIdle, the callback function
+should also return a true (non-zero) value if it is intended to be called
+again, otherwise it should return a false (zero) value.

+Clipping region - abstract base class.
+This abstract base class represents a 2-dimensional area which is used by
+Graphics, the graphics window server, and the text window server to define
+regions of the display which need to be updated, or regions within which all
+operations must occur.
+A TRegion is defined in terms of an array of TRects and the more complex the
+region, the more TRects are required to represent it.
+A clipping region initially has space allocated for five rectangles.
+If manipulations result in a region which requires more than this, an attempt
+is made to allocate more rectangles. If this cannot be done, an error flag
+is set, and all subsequent operations involving the region have no effect
+(except possibly to propagate the error flag to other regions).
+The CheckError() member function allows
+the error flag to be tested; Clear() can be used to clear it.
+The redraw logic of application programs may use the TRegion in various ways:
+1. minimally, they pass it to the graphics context as the clipping region; when
+a graphics context is activated to a window, the clipping region is set up
+automatically
+2. if they wish to avoid redrawing objects which are outside the general area
+of the region, they may use TRegion::BoundingRect() to return the rectangle
+which bounds the clipping region, and draw only primitives that lie within
+that rectangle
+3. if they wish to exercise finer control, they may extract the individual rectangles
+that comprise the clipping region using Operator[]().
+Application programs may also manipulate clipping regions in order to constrain
+parts of their redrawing to narrower areas of the screen than the clipping
+region offered by the window server. To do this, functions that allow clipping
+region manipulation may be used; for example, adding or removing rectangles
+or finding the intersection or union of two regions.
