On Windows, add API call saying that tk scales for DPI. On Windows 8.1+ or 10, with DPI compatibility properties of the Python binary unchanged, and a monitor resolution greater than 96 DPI, this should make text and lines sharper. It should otherwise have no effect.
Clicking on a context line moves that line to the top of the editor window.
IDLE: Use read-only text widget for code context instead of label widget.
