Cursor highlighter

Cursor highlighter is a minimalist app for cursor highlighting. A circle is drawn around the cursor, which has changeable size, color, and transparency at run time.

The application is written in WPF, and its operation is very simple - it creates a transparent window with an ellipse around the cursor. The position updating is handled by DispatcherTimer, which periodically queries the cursor position and changes the position of the highlighting ellipse window accordingly. The cursor position is acquired using System.Window­s.Forms.Cursor­.Position, so no low-level WinAPI calls are needed.
