======================================
bpo-33768: Clicking on a context line moves that line to the top
of the editor window.
bpo-33763: Replace the code context label widget with a text widget.
bpo-33664: Scroll IDLE editor text by lines.
(Previously, the mouse wheel and scrollbar slider moved text by a fixed
number of pixels, resulting in partial lines at the top of the editor
box.) This change also applies to the shell and grep output windows,
but currently not to read-only text views.
bpo-33679: Enable theme-specific color configuration for Code Context.
(Previously, there was one code context foreground and background font
color setting, default or custom, on the extensions tab, that applied
to all themes.) For built-in themes, the foreground is the same as
normal text and the background is a contrasting gray. Context colors for
custom themes are set on the Hightlights tab along with other colors.
When one starts IDLE from a console and loads a custom theme without
definitions for 'context', one will see a warning message on the
console.
bpo-33642: Display up to maxlines non-blank lines for Code Context.
If there is no current context, show a single blank line. (Previously,
the Code Contex had numlines lines, usually with some blank.) The use
of a new option, 'maxlines' (default 15), avoids possible interference
with user settings of the old option, 'numlines' (default 3).
bpo-33628: Cleanup codecontext.py and its test.
bpo-32831: Add docstrings and tests for codecontext.py.
