// Module Overview: Starboard EGL API

//

// The EGL API provides an interface with accompanying type declarations and

// defines that together provide a single consistent method of EGL usage across

// platforms.

//

// This API is designed to abstract the differences between EGL implementations

// and versions on different systems, and to remove the requirement for any

// other code to directly pull in and use these system libraries.

//

// # EGL Version

//

// This API has the ability to support EGL 1.5, however it is not required to

// support anything beyond EGL 1.4. The user is responsible for ensuring that

// the functions from EGL 1.5 they are calling from the interface are valid.
