Crate glium_text_rusttype

This crate allows you to easily write text.

Usage:

// The `TextSystem` contains the shaders and elements used for text display.
let system = glium_text::TextSystem::new(&display);

// Creating a `FontTexture`, which a regular `Texture` which contains the font.
// Note that loading the systems fonts is not covered by this library.
let font = glium_text::FontTexture::new(
    &display,
    File::open("font.ttf").unwrap(),
    32,
    glium_text::FontTexture::ascii_character_list()
).unwrap();

// Creating a `TextDisplay` which contains the elements required to draw a specific sentence.
let text = glium_text::TextDisplay::new(&system, &font, "Hello world!");

// Finally, drawing the text is done like this:
let matrix = [[1.0, 0.0, 0.0, 0.0],
              [0.0, 1.0, 0.0, 0.0],
              [0.0, 0.0, 1.0, 0.0],
              [0.0, 0.0, 0.0, 1.0]];
glium_text::draw(&text, &system, &mut display.draw(), matrix, (1.0, 1.0, 0.0, 1.0));

FontTexture will rasterize exact characters it's told to. It can be passed anything that implements IntoIterator<char> trait. It is possible to use chained ranges with it like this: (0 .. 0x7f+1).chain(0x400 .. 0x4ff+1).filter_map(std::char::from_u32)

This will rasterize font with characters from "Basic Latin" and "Cyrillic" sets. Here is a complete list of ranges with description.

As of now, Rust doesn't provide a way to create inclusive ranges yet so thou shall add +1 to the outer bound.
