Pocket Paint Flutter: antialiasing and smoothing (advanced options)

Pocket Paint is a drawing app currently being rewritten in Flutter. The original Android app includes advanced options like antialiasing and stroke smoothing, which help users create clean, high-quality artwork. However, these features are currently missing in the new Flutter version. This project will bridge that gap by bringing these advanced drawing capabilities to the new app. The final deliverables will include a native-matching "Advanced Options" UI menu, the integration of smoothing and antialiasing across all drawing tools (such as the Brush, Eraser, and Shapes), and ensuring that all artwork saves correctly and remains compatible with older Catrobat project files.
