+
+Still Very Problematic
+----------------------
+
+  _Coordinating system._
+
+
+What is really needed with calendar?
+
+
+   while (yearHasMonthsLeft):
+
+      // draw month skeleton
+      draw skeleton( height[month] )
+      // height(weeks) is one of the arguments
+
+
+      // put text in correct places 
+      move to non empty day from beginning
+
+      while ( monthHasDaysLeft):
+         putText ( date)
+
+         etc..
+
+
+ * So, where is scaling done?
+ * Is calendar fixed size? 
+
+How it is used?
+
+   -Someone needs a piece of calendar(x0,y0, x1,y1)
+      -Calculate what part needs rendering
+      -Render
+      -Put on screen with right coordinates.
+
