k( rddlmZ eddd yy)a codecontext - display the block context above the edit window
Once code has scrolled off the top of a window, it can be difficult to
determine which block you are in. This extension implements a pane at the top
of each IDLE edit window which provides block structure hints. These hints are
the lines which contain the block opening keywords, e.g. 'if', for the
enclosing block. The number of hint lines is determined by the maxlines
variable in the codecontext section of config-extensions.def. Lines which do
not open blocks are not shown in the context hints pane.
For EditorWindows, <<toggle-code-context>> is bound to CodeContext(self).

Initialize settings for context block.
editwin is the Editor window for the context block.
self.text is the editor window text widget.
self.context displays the code context text above the editor text.
Initially None, it is toggled via <<toggle-code-context>>.
self.topvisible is the number of the top text line displayed.
self.info is a list of (line number, indent level, line text,
block keyword) tuples for the block structure above topvisible.
self.info[0] is initialized with a 'dummy' line which
starts the toplevel 'block' of the module.
self.t1 and self.t2 are two timer events on the editor text widget to
monitor for changes to the context text or editor font.

The tuple fields are (linenum, indent, text, opener).
The list represents header lines from new_topvisible back to
stopline with successively shorter indents > stopindent.
The list is returned ordered by line number.
Last indent returned is the smallest indent observed.

No update is done if the text hasn't been scrolled. If the text
was scrolled, the lines that should be shown in the context will
be retrieved and the context area will be updated with the code,
up to the number of maxlines.
