В блоке Pass просто кусок CG-шейдера, он не Unity-specific? Т.е. точно такой же код можно использовать в другом движке, поддерживающем CG? vert и frag - это зарезервированные имена? Там нет техник, как в HLSL?

Это не новая технология шейдеров да, в данном случае Pass и есть "техника". Несколько пассов - несколько "техник". В директивах указывается, какая функция является вершинной, какая фрагментной ( #pragma vertex vert и #pragma fragment frag). На основе этих директив собирается шейдер.
Вот такая хренатень генерируется:
PHP код:

_HorisontalSpeed ("Horisontal Speed", Range(0,10)) = 1
_VericalPeriod ("Verical Period", Range(1,20)) = 1
_HorisontalPeriod ("Horisontal Period", Range(1,20)) = 1
_VericalAmplitude ("Verical Amplitude", Range(0,1)) = 0.5
_HorisontalAmplitude ("Horisontal Amplitude", Range(0,1)) = 0.5
