|
||||
- Fonts: Functions with a 'float size_pixels' parameter can accept zero if it is set in ImFontSize::SizePixels.
|
||||
- Fonts: Prefer using U+FFFD character for fallback instead of '?', if available. (#4269)
|
||||
- Fonts: Use U+FF0E dot character to construct an ellipsis if U+002E '.' is not available. (#4269)

- Fonts: Add U+FFFD ("replacement character") to default asian glyphs ranges. (#4269)
|
||||
- Demo: Fixed requirement in 1.83 to link with imgui_demo.cpp if IMGUI_DISABLE_METRICS_WINDOW is not set. (#4171)
|
||||
Normally the right way to disable compiling the demo is to set IMGUI_DISABLE_DEMO_WINDOWS, but we want to avoid
|
||||
implying that the file is required.
