Pull Request Overview

This PR refactors drawing routines in PaperAndPencil.java to improve code reuse and consistency in mathematical function calls. Key changes include:

• Replacing p.TWO_PI with PConstants.TWO_PI for a constant reference.
• Introducing helper methods (setupDrawingState and setFillWithAlpha) to centralize drawing state setup.
• Changing instance-based math calls (e.g., p.cos, p.sin, p.lerp, p.dist) to use their static PApplet counterparts.

• Review the change from using the instance-based p.cos() to the static PApplet.cos(); ensure that the static method provides behavior equivalent to the instance method, particularly if the PApplet instance has custom state or behavior.

x = centerX + diameter/2 * PApplet.cos(theta);

• Verify that replacing the instance method p.dist() with the static PApplet.dist() does not bypass any instance-specific behavior or adjustments in distance calculations.

float increment = 0.15f / PApplet.dist(x1, y1, x2, y2);
