Bumps cairosvg from 2.1.3 to 2.5.1.

Release notes

Sourced from cairosvg's releases.

2.5.1

WARNING: this is a security update.

When processing SVG files, CairoSVG was using two regular expressions which are vulnerable to Regular Expression Denial of Service (REDoS).

If an attacker provided a malicious SVG, it could make CairoSVG get stuck processing the file for a very long time.

Other bug fixes:

• Fix marker positions for unclosed paths
• Follow hint when only output_width or output_height is set
• Handle opacity on raster images
• Don’t crash when use tags reference unknown tags
• Take care of the next letter when A/a is replaced by l
• Fix misalignment in node.vertices

2.5.0

• Drop support of Python 3.5, add support of Python 3.9.
• Add EPS export
• Add background-color, negate-colors, and invert-images options
• Improve support for font weights
• Fix opacity of patterns and gradients
• Support auto-start-reverse value for orient
• Draw images contained in defs
• Add Exif transposition support
• Handle dominant-baseline
• Support transform-origin

2.4.2

• Fix race condition in tests
• Fix scale for images with no viewBox

2.4.1

• Fix the --scale parameter
• Allow href attributes with no namespace
• Fix the tree root detection

2.4.0

• Fix aspect and position when resizing root SVG tag
• Follow aspect and position hints when using forced output size

2.3.1

• Fix relative paths on Windows

2.3.0

• Drop Python 3.4 support
• Make text selectable on generated PDF files
• Don't inherit dx and dy attributes
• Fix support of alignment-baseline="hanging"
