       - Arrays of arrays are now supported, as per the GL_ARB_arrays_of_arrays extension.
       - Compute shaders are now supported, as per the GL_ARB_compute_shader extension.
       - Added imageSize() built-ins to query the dimensions of an image.
-      - Define robust out-of-bounds access behavior when enabled, as per the GL_ARB_robust_buffer_access_behavior extension.
       - All choice of depth or stencil texturing, for a packed depth-stencil texture, as per the 
         GL_ARB_stencil_texturing extension.
       - Allow explicit locations/indexes to be assigned to uniform variables and subroutines, as per the
