Overview
--------
-Calendar is a renderable which generates an annual calendar.
+Calendar is a renderable which can be used to generate an annual calendar.
This is one of the vital components in PP-module/project.
Basics
------
-One calendar is one year. Usually only parts of it are shown.
+One calendar is one month. Usually only parts of it are shown.
+The whole month is rendered every time.
Issues
------
-What is needed for Calendar?
+What is needed from framework to render Calendar?
- -Coordinating system::

+ -object => window

+
+ -Text ratio, (Form/layout):
+ -Text's ratio to month's calendar skeleton *must* be
+ changeable from java side.
-Localization:
-Months and Weekdays.
-Solve in java side.
- -Speed
- -Render with OpenGL in C++ side
- -Use cpu wisely and draw only needed parts.

-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?
+Why CalendarVob isn't made with CallGL?
- -Someone needs a piece of calendar(x0,y0, x1,y1)
- -Calculate what part needs rendering
- -Render
- -Put on screen with right coordinates.
-
+ -Text is very problematic - can't be done.
