# GLES 3.x functions required by the translator library.
# Right now, this is used for:

# - glGetStringi() from the host GL library in order to
#   deal with the fact that glGetString(GL_EXTENSIONS) is obsolete.
#   In OpenGL 3.0, some drivers don't implement it anymore.
#   (i.e. the # function just returns NULL).
# - glFenceSync / glClientWaitSync / glWaitSync to enforce frame
#   ordering while preserving performance, and to implement
#   KHR_fence_sync and KHR_ANDROID_native_fence_sync extensions.
