Add alpha of usage example

[Abod-A]

Description

The example draws five rectangles of the same red color at increasing alpha values (50, 100, 150, 200, 255) over a light blue background stripe, making the transparency effect clearly visible. The alpha value of each color is read back using alpha_of and displayed below its rectangle.

Great work on this PR! The usage examples are clear, practical, and consistent across C++, Python, and C# implementations. I like that each example demonstrates a realistic use case, making it easier for learners to understand how the API functions are intended to be used. The accompanying screenshots/GIFs and description files add valuable context and improve the overall learning experience. The code is well organised, easy to follow, and aligns with the existing project structure.

One minor suggestion would be to ensure comments and descriptive text remain consistent across all language versions so that users receive the same guidance regardless of the language they choose. Other than that, I didn't identify any issues, and the implementation looks complete and well documented. Great job!

Approved. The implementation is clean, consistent, and follows the project's documentation and usage example standards. Nice work!

Great work! The implementation is clear, consistent across the supported languages, and demonstrates alpha_of well.

One small suggestion: consider making the .txt description a little more descriptive by mentioning that alpha_of reads and displays the alpha value of each colour. It would make the purpose of the example even clearer for users.

Approved.
