As seen in the FreeType documentation, there is a render mode for creating SDFs. This enum is missing in the rust binding as of yet

For anyone stumbling upon this you can set the render SDF flag with the following

let load_flags = freetype::face::LoadFlag::from_bits((0x1 << 2) | ((5 & 15) << 16)).unwrap();

Where:

1. 0x1 << 2 is equivalent to LoadFlag::RENDER
2. ((5 & 15) << 16) is equivalent to FT_LOAD_TARGET_(FT_RENDER_MODE_SDF) in C

Then you can use the load_flags with load_glyph() or load_char().
