Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the starfield application by introducing comprehensive support for 2x resolution displays, ensuring a visually consistent and optimized experience across different screen densities. Additionally, it updates the default background color to black, providing a darker initial aesthetic for the starfield.

Highlights

• 2x Resolution Support: Enabled support for 2x resolution displays, allowing the starfield application to render at higher densities.
• Default Background Color Change: The default background color for the starfield application has been changed to black.
• Dynamic Scaling of Parameters: Various visual and animation parameters, such as dimensions, delays, frame counts, star radii, and star counts, now dynamically adjust based on the detected display resolution (1x or 2x).

Changelog

• apps/starfield/manifest.yaml
  • Added the supports2x: true flag to the manifest to indicate 2x resolution compatibility.
• apps/starfield/starfield.star
  • Imported the canvas module from render.star to access display properties.
  • Dynamically set WIDTH, HEIGHT, DELAY, FRAMES, MIN_RADIUS, and MAX_RADIUS based on canvas.width(), canvas.height(), and canvas.is2x() to scale correctly.
  • Changed DEFAULT_BACKGROUND_COLOR from 0 to 1, setting the default to black.
  • Adjusted DEFAULT_STAR_COUNT and the display text for '25' and '50' star count options to be resolution-aware.
  • Introduced MOVE_INCR_TAIL_AMOUNT constant, scaled by the detected resolution, to control star speed increments.
  • Updated the move_star function to use MOVE_INCR_TAIL_AMOUNT for consistent star movement across resolutions.
