// Module Overview: Starboard GLES API
//
// The GLES API provides an interface with accompanying type declarations and
// defines that together provide a single consistent method of GLES usage across
// platforms.
//
// This API is designed to abstract the differences between GLES implementations
// and versions on different systems, and to remove the requirement for any
// other code to directly pull in and use these system libraries.
//
// # GLES Version
//
// This API has the ability to support GLES 3.0, however platforms are not
// required to support anything beyond GLES 2.0. The caller is responsible for
// ensuring that the functions from GLES 3.0 they are calling from the interface
// are valid.
