GL: Do not support ETC1 textures on Desktop GL As pointed out in WebGL issue 3014, ANGLE has been exposing ETC1 texture support on desktop GL when GL_ARB_ES3_compatibility or GL 4.3+ is available. However, it is very likely that none of these platforms actually have hardware support for this format, and are only supporting it for compatiblity with ES3. We shouldn't expose this so that desktop clients can use a better format instead.
