%description
This is a new, essentially complete implementation of a cairo backend for
Matplotlib. It can be used in combination with a Qt5, GTK3, Tk, wx, or macOS
UI, or noninteractively (i.e., to save figure to various file formats).
Noteworthy points include:
  - Improved accuracy (e.g., with marker positioning, quad meshes, and text
    kerning).
  - Support for a wider variety of font formats, such as otf and pfb, for vector
    (PDF, PS, SVG) backends (Matplotlib's Agg backend also supports such fonts).
  - Optional support for complex text layout (right-to-left languages, etc.)
    using Raqm.
  - Support for embedding URLs in PDF (but not SVG) output.
  - Support for multi-page output both for PDF and PS (Matplotlib only supports
    multi-page PDF).
  - Support for custom blend modes (see `examples/operators.py`).
