zignal 0.3.0

Highlights

This release focuses on text rendering capabilities and significantly expands the Python bindings to provide a complete 2D graphics API. The font support enables rendering text in various bitmap formats, while the Python Canvas API brings drawing capabilities on par with the core library.

Core Improvements

• Unified Point syntax: Cleaner API with Point(2, f32) instead of Point2d(f32)
• Image scaling: New method for flexible image resizing
• PixelIterator: Sequential pixel traversal with view support
• Canvas bounds handling: Better clipping and edge case management
• Matrix enhancements: Improved numerical stability in decompositions

Font Support & Text Rendering

• New font system: Load and render text using PCF and BDF bitmap fonts
• Font compression: Automatic support for gzipped font files
• Built-in font: Default 8x8 font for immediate text rendering
• Canvas text drawing: Render text with optional antialiasing

Python Bindings - Major Expansion

• Canvas API: Complete 2D drawing primitives - lines, circles, polygons, rectangles, Bézier curves
• Geometry classes: Rectangle operations and ConvexHull computation
• Text rendering: BitmapFont class for rendering text in Python
• Enhanced Image class: Richer API with better Canvas integration
