This directory contains OpenGL ES and EGL extension specifications that have been or are being defined for Android. The table below tracks usage of EGL enumerant values that have been reserved for use by Android extensions. See https://github.com/KhronosGroup/EGL-Registry/blob/master/api/egl.xml for a list of all enumarant values currently reserved and registered with Khronos.
