-> GlyphRanges

Using fonts

pushFont :: MonadIO m => Font -> m ()

Pushes a font into the parameters stack, so ImGui would render following text using it.

popFont :: MonadIO m => m ()

Pops a font pushed into the parameters stack

Should be called only after a corresponding pushFont call.

Atlas management

clearFontAtlas :: MonadIO m => m ()

Clear all font atlas input and output data

buildFontAtlas :: MonadIO m => m ()

Explicitly build pixels data for the atlas.
