  Message : EGL: Remove egl::Error from validation code. Instead of using an egl::Error return value, errors are recorded on the egl::Thread immediately at the call site. This makes the code work the same way as in the GL entry points. Updates the EGL "try" macros to include a special handler for the EGL validation entry points. Uses a special ValidationContext helper class to preserve the existing info.
