Do not try to use GL_texture_rectangle on GL ES

Browse Source 
Do not try to use ARB_GL_texture_rectangle on GL ES.
Command buffer exposes it, but it's not recommended. It also
does not work with TexImage2D, and ANGLE does not
have support for it on with GL ES 3.0 source context.

Bug triggered only when trying to use command buffer in
GL ES 3.0 mode.
