support 32-bits indices. Most examples back-ends have been modified to support the VtxOffset field.
|

- ImDrawList: Added ImDrawCmd::IdxOffset value, equivalent to summing element count for each draw command.

This is provided for convenience and consistency with VtxOffset.

- ImFontAtlas: FreeType: Added RasterizerFlags::Monochrome flag to disable font anti-aliasing. (#2545)

Combine with RasterizerFlags::MonoHinting for best results.

- ImFontGlyphRangesBuilder: Fixed unnecessarily over-sized buffer, which incidentally was also not
