// vertex stage we couldn't use createTestForStage functions - we need a custom
// version for both vertex and fragmen shaders at the same time. This was required
// as we needed to pass result from vertex stage to fragment stage where it could
// be saved to ssbo. To achieve that InstanceContext is created manually in
// createInstanceContext method.
