// 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.
