1. Reduce glyphs ranges by calculating them from source localization data.
You can use the `ImFontGlyphRangesBuilder` for this purpose, this will be the biggest win!
2. You may reduce oversampling, e.g. `font_config.OversampleH = font_config.OversampleV = 1`, this will largely reduce your texture size.
2. You may reduce oversampling, e.g. `font_config.OversampleH = 2`, this will largely reduce your texture size.
Note that while OversampleH = 2 looks visibly very close to 3 in most situations, with OversampleH = 1 the quality drop will be noticeable.
3. Set `io.Fonts.TexDesiredWidth` to specify a texture width to minimize texture height (see comment in `ImFontAtlas::Build()` function).
4. Set `io.Fonts.Flags |= ImFontAtlasFlags_NoPowerOfTwoHeight;` to disable rounding the texture height to the next power of two.
5. Read about oversampling [here](https://github.com/nothings/stb/blob/master/tests/oversample).
