~duangle/scopes#15: 
When using GLSL version 420, spir-v generator doesn't insert GL_ARB_shader_storage_buffer_object extension

repro:

fn vertex ()
    using import glsl
    using import glm
    buffer attr :
        struct Attributes plain
            data : (array vec2)
    gl_Position = (vec4 (attr.data @ gl_VertexID) 0 1)
fn fragment ()
    using import glsl
    using import glm
    out fcolor : vec4
    fcolor = (vec4 1)
    
# use your own link-shader fn here
let program = 
    link-shader
        static-compile-glsl 420 'vertex (static-typify vertex)
        static-compile-glsl 420 'fragment (static-typify fragment)
        
# will yield this runtime (OpenGL) error:
#0:3(16): error: syntax error, unexpected NEW_IDENTIFIER

# it can be solved by patching in (inserts after the #version line):
let vsource =
    patch-shader
        static-compile-glsl 420 'vertex (static-typify vertex)
        "#extension GL_ARB_shader_storage_buffer_object : require\n"
