Description

Fix #397

This pull request addresses a bug in how clipping paths are applied when rendering text with a positional offset, ensuring that clip paths are correctly transformed into the text's local coordinate space. It also adds comprehensive regression tests to validate the fix for various boolean clip operations and provides new reference images for test verification.

Bug Fixes:

• Corrected the transformation of clipPaths in DrawingCanvas<TPixel>.CreateTextCompositionCommand so that when text is rendered with a non-zero RenderLocation, the clip paths are translated into the glyph-local coordinate space, ensuring correct clipping behavior. [1] [2] [3]

Testing Improvements:

• Added a new test class Issue_397 to cover scenarios where text is drawn with intersecting and non-intersecting clipping paths using all boolean operations, validating both the fix and expected rendering output.
• Added reference output images for all test cases in Issue_397 to support regression testing and visual verification. [1] [2] [3] [4] [5] [6] [7]
