The tunnel screensaver was drawing characters at coordinates outside of the terminal's visible area. This caused some terminals to clamp the coordinates, resulting in persistent lines being drawn at the edges of the screen, which disrupted the visual effect. This commit refactors the drawing logic to introduce `plot_point` and `erase_point` helper functions. These functions perform boundary checks to ensure that characters are only drawn within the visible screen area, which resolves the visual artifacts.

The tunnel screensaver had persistent lines on the left and bottom of the screen. This was caused by drawing outside the screen boundaries. This commit fixes the issue by adding boundary checks before drawing.
