Cargo Features

vk-rs has no features set by default.

[dependencies]
vk-rs = { version = "0.1.4", features = ["win32", "xlib", "android"] }
win32 = winapi
xlib = x11
xcb wayland android

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality [may be removed in the future](https://rust-lang.github.io/rfcs/3491-remove-implicit-features.html).

winapi win32?
x11 xlib?
