## Commit Message
[Module][Feature]: [Title]

[Description]

- [Module] refers to the sub-module primarily affected by your change. Most of the time, this indicates the name of a sub-folder.
This also suggests who might need to review your patch.
If your change doesn't belong to any sub-modules, you can either replace this with a suitable name or skip it.
The name should be written entirely in lowercase letters.
  - e.g., build, doc, infra, common, sw_engine, gl_engine, svg_loader, examples, wasm, svg2png...

- [Feature] indicates the primary function or feature you modified. Typically, this represents a class or file name.
This is an optional.
  - e.g., canvas, shape, paint, scene, picture, task-scheduler, loader, builder, ...

- [Title] provides a brief description of your change and should be encapsulated in a single sentence.
  - e.g., "Fixed a typo."
  - e.g., "Addressed compile warnings."
  - e.g., "Refactored code."
  - e.g., "Resolved a rendering bug causing overlapped shapes to display improperly."

- [Description] doesn't have a strict format. However, it should detail what you accomplished in this patch as comprehensively as possible.

 If you've resolved bugs, include the following details:
  - The type of bug.
  - Steps to reproduce it.
  - The root cause.
  - The solution applied.

  For new features or functions, cover:
  - The nature of the feature.
  - Full API specifications (if there are any API additions).
  - Its necessity or rationale.
  - Any conditions or restrictions.
  - Relevant examples or references.

 Finally, include any related issue ticket numbers in this section, if applicable.


Here's a sample commit message for clarity:

- renderer/paint: Introduced path clipping feature

  We've added a new method, Paint::composite(), to support various composite behaviors. This allows paints to interact with other paint instances based on the chosen composite method. Initially, we're introducing the "ClipPath" method for path-based clipping.

  targetPaint->composite(srcPaint, CompositeMethod::ClipPath);

  Note: If the source paint lacks path information, clipping may not produce the desired effect.

  @API Additions:
  enum CompositeMethod {None = 0, ClipPath};
  Result Paint::composite(std::unique_ptr<Paint> target, CompositeMethod method) const noexcept;

  @Examples: Introduced ClipPath

  @References: [Provide any relevant links, such as screenshots.]

  @Issues: [Link to the issue]
