gfx example not working

[vignesh-sankaran]

When running cargo run --example gfx, the error thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: "gfx_app: Syntax error in Cargo.toml for url `https://raw.githubusercontent.com/gfx-rs/gfx/master/Cargo.toml`\nError #1001, Expected: `[package]`\n14: ]\n15,1: \n15,1: ^\n"', src/libcore/result.rs:906:4 appears.

Looking into this error, it turns out that this file uses the [workspace] tag, when the specification file for Cargo.toml files doesn't include a specification for this tag.

Right now, the gfx project is going through a lot of work and will have breaking changes when it gets updated. When the ecosystem gets updated, the issue can be worked on then.
