// From section 7.1 (Built-In Language Variables) of the GLSL 4.10
// spec:
//
// If a built-in interface block is redeclared, it must appear in
// the shader before any use of any member included in the
// built-in declaration, or a compilation error will result.
//
// This appears to be a clarification to the behaviour established for
// gl_PerVertex by GLSL 1.50, therefore we test it using GLSL version
// 1.50.
//
// In this test the variable that we attempt to use before redeclaring
// gl_PerVertex is not included in the redeclaration of gl_PerVertex.
