Minor API conveniences I want to add

[icefoxen]

Impl Default for SamplerInfo and the types it contains. ViewKind as well? MipLevel? Look at TextureBuilder::new() for preferred values.

Refactor sprite example to have a separate method for creating textures?

Can Mesh and Image be Clone?

Things that need docs: resource::Kind,

[zakarumych]

resource::Kind is gfx_hal::image::Kind reexported.
Shouldn't be that way.

[icefoxen]

SamplerInfo and ViewKind are also part of gfx-hal. Will submit enhancements to them.

Mesh can't be Clone because it contains a Buffer and IndexBuffer, which need destruction via free_buffers() or whatever. Might be convenient to add a method that creates a copy of a mesh anyway, even if it has to take a queue and factory to do it. ...that said you can't really modify an existing mesh, so why would you want an exact copy of it instead of just reusing it? Maybe to make resource management easier. Same goes for Image; it can't be Clone 'cause it contains GPU-managed data, but being able to make a copy or near-copy of an existing image might be handy.

Actually, Mesh contains Escape<Buffer<B>> but just IndexBuffer<B>. Should the index buffer be wrapped in an Escape too? Looks like it, or its underlying Buffer, could be.

[zakarumych]

IndexBuffer is just Escape<Buffer<B>> + IndexType.

I can't see use case for copying meshes and images, but it can be easy implemented as stand-alone function. Although stand-alone function suffers from bad discoverability.

Derp, I could have sworn that I saw IndexBuffer containing just a Buffer<B> with no Escape.
Okay, I think that's all. Thank you!
