v4.7.3

[4.7.3] - 2025-09-12

Changed

• ggsave(): Large plot dimensions without units now require explicit unit specification.
  
  When plot size exceeds 20 without specifying units (e.g., ggsave(p, 300, 400)),
  
  we ask to specify units explicitly:
  
  ggsave(p, 300, 400, unit='px') or ggsave(p, 3, 4, unit='in').

Fixed

• ggtb() support in Swing/Batik frontend.
• Multiline support for axis labels in polar coordinates.
• When the plot size in ggsave() is specified in pixels, dpi now affects
  
  only the physical size, not the pixel dimensions as before.
• Blocking SwingUtilities.invokeAndWait() call in plot image export (AWT backend)
