Use CFG Aliases to Replace the backends! Macro Uses the `cfg_aliases` crate to replace the `backends!` macro and provide a more natural way to gate backend specific code. 2020-08-30 02:40:07 +00:00			`fn main() {`

Add pervasive Naga support to shader module loading The purpose of the PR is to support Naga modules everywhere. As a requirement, it updates the gfx-rs version used. Most of the logic is dedicated towards building a shader interface, where previously we just used naga's IR. Now we have our own mini-IR. 2020-12-03 05:30:38 +00:00			`apple: { any(target_os = "ios", target_os = "macos") },`
