Added AsRawFd impl for RawTerminal

See merge request redox-os/termion!170

feature: changing cursor style

See merge request redox-os/termion!164

fix warnings

See merge request redox-os/termion!165

fix CI config

See merge request redox-os/termion!167

Avoid allocating temporary Strings in Display implementations

See merge request redox-os/termion!168

Make the keys return their inner error, if any.

See merge request redox-os/termion!162

Add terminal_size_pixels() to expose terminal's pixel size

See merge request redox-os/termion!163

Make the keys return their inner error, if any. For example, when permission to access the TTY is denied, don't loop infinitely and instead return to the outer scope to error and exit (or not) there.

Backtab key

See merge request redox-os/termion!157

Use stdout to get and set terminal attributes

See merge request redox-os/termion!161

Make Color extend Debug

See merge request redox-os/termion!159

Add a HideCursor wrapper type acting like AlternateScreen

See merge request redox-os/termion!154

Fix TIOCGWINSZ type mismatch on DragonFly

See merge request redox-os/termion!152

Below is the error message I got before this patch:

    error[E0308]: mismatched types
      --> src/sys/unix/size.rs:17:34

    17 |         cvt(ioctl(STDOUT_FILENO, TIOCGWINSZ, &mut size as *mut _))?;
       |                                  ^^^^^^^^^^ expected u64, found u32
    help: you can cast an `u32` to `u64`, which will zero-extend the source value
