Version 0.6

[kvark]

Closes #745
Has all the changes from 0.6 branch, merged with upstream.
GL device: https://github.com/gfx-rs/gfx_device_gl/pull/42
Glutin window: https://github.com/gfx-rs/gfx_window_glutin/pull/13
GLFW window: https://github.com/gfx-rs/gfx_window_glfw/pull/8
Examples: https://github.com/gfx-rs/gfx_examples/pull/30

Major changes:

• now using crates.io internally for dependencies. Users are encouraged to also use it, we may not guarantee any stability in the Git tree.
• batch context is removed as well as all the relevant batch types. Please use batch::Core or batch::Full.
• texture kinds enum is totally changed
• Renderer::update_* calls now error out instead of panicking
• gfx_device_gl::Factory implements Clone instead of gfx_device_gl::Device::spawn_factory

Hmm there is a problem... The parameter link we generate now in gfx_parameters! is a tuple. We want it to be clonable, but the Clone is only implemented for a limited tuple size, while our parameters may exceed it (and that actually happens in the deferred example)...

Edit: I have a temporary solution, need to pack the tuple better

LGTM. We will need to merge and publish in sequence. I can't publish it until this afternoon.

@csherratt I'd also like to provide Device::create_factory before merging. Wondering now if it's going to complicate any code... since Factory will need to be an associated type of the Device.

[LaylConway]

Why does Device create a factory rather than Factory creating more factories, since you get a factory at initialization?

[kvark]

@LaylConway excellent point! Instead of create_factory we can just have Clone implemented by gfx_device_gl::Factory and the user code binding F: Factory<R> + Clone where needed.

We don't exactly have a factory at initialization though. There is gfx_device::gl::Device::new() that is called by gfx_window_* crates, and then the factory is created via create_factory. Changing it to cloning would require us to bring back gfx_device_gl::create() method as we had prior to 0.5.

[kvark]

@csherratt I think we are ready now.
