10/// Request for usage of high performance gpu in multi gpu setups.
11///
12/// # Platform behavior:
13///
14/// ## Windows:
15/// * Adds the variables `NvOptimusEnablement` and `AmdPowerXpressRequestHighPerformance` with a value of one.
16/// * Required the user to also export those by setting the linker args. This can be done in build.rs via:
17/// ```rust
18/// println!("cargo:rustc-link-arg=/EXPORT:NvOptimusEnablement");
19/// println!("cargo:rustc-link-arg=/EXPORT:AmdPowerXpressRequestHighPerformance");
20/// ```
21///
22/// ## Other platforms:
23///
24/// Currently does nothing on other platforms.
25///
26/// # Validating
27///
28/// Check with dumpbin /exports $APPLICATION.exe
