| // 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. |
