Commit c6d2b331ea16a9712fb10ca39b78d0f3d2a19d37

Key Changes:

1. Dependency Update: The patch update the Cargo.toml file to replace the rusttype dependency with ab_glyph.
2. Font Handling: Changes were made in draw_detections.rs and default_font/mod.rs to use ab_glyph instead of rusttype for font handling.
3. Coding Patterns: Updated some code patterns in functions related to image processing to improve maintainability.

Potential Problems:

1. Dependency Compatibility: Make sure that the project is compatible with the ab_glyph dependency and that it works correctly in the existing code.
2. Font Handling: While updating font handling to use ab_glyph, ensure that the font functionality still works as expected after the change.
3. Code Patterns: Verify that the changes in code patterns do not introduce new bugs or unintended behavior. It's crucial to test these functions thoroughly.

Overall, the changes seem reasonable and focused on resolving compile errors, but thorough testing is recommended to ensure everything functions as intended.
