This module implements a graphic clock that is displayed as a dial with hands.  The size of the clock is determined dynamically according to the space allowed  for the containing viewer.  The clock will display and update a second hand when it is large (non-iconic), and at all times will display and update minute and hour hands.  Options are provided to invert the clock, and to change the offset of the hour (mostly for fun).  The user may have multiple clocks on the screen.
Besides telling the time in an attractive manner, this module provides an example of a user-written Viewers class, and a simple use of Cedar Graphics.  It also provides some stylistic guidelines for writing monitors (such as UNWIND => NULL), processes (handling ABORTED), and suggests an indentation style for Mesa.
A MyData object is used to retain state used in updating the clock.
EnterPaint claims the paint lock, returns FALSE if the viewer has died.
ExitPaint releases the paint lock, ignore NIL data (could be a destroy race).
AddMeToList atomically adds a clock to the current list.
Wait for a clock list change.
[self: Viewer, context: Graphics.Context, whatChanged: REF, clear: BOOL]
PaintMe is called to repaint the clock (we do try to minimize the work involved).
TickMark is used to paint a single tick mark.  It just puts a rectangle at the position given by seconds.  We include extra comments to explain Graphics usage.
Face is used to draw a clock face (a circle).
add to the path
DrawTime is called to draw the new time.  We assume that the old time is the one currently displayed.
Handy draws a hand at the position given by seconds (not necessarily integral), where the length and width are normalized to a radius of 1.  If invert, we are actually erasing an old hand.
force inversion of the hands
rotate to proper angle
enter the path
not a simple line, but a triangle
erase the hands
erase the second hand
erase the minute hand
erase the hour hand
draw the hands
init the face    
draw the tick marks
draw the hands
[parent: REF, clientData: REF, mouseButton: MouseButton, shift, control: BOOL]
SwapColor swaps the foreground & background colors.
[parent: REF, clientData: REF, mouseButton: MouseButton, shift, control: BOOL]
ChangeOffset changes the hour offset (red back, blue forward, yellow zeros offset)
[parent: REF, clientData: REF, mouseButton: MouseButton, shift, control: BOOL]
We keep a list of the created clocks (it is not really needed by anyone, but can help debugging).
Mother gives the extra level of frame needed to handle ABORTED properly.
This procedure just loops, repainting the clock as the time changes.  We only return when the clock viewer is destroyed.
Just pause for the appropriate time.  The pause should be long enough to not burden the processor and short enough to keep the second hand update smooth.
Start up one clock.
Start up n clocks, iconic by default.
