Running the following case list:
causes compile_shader and delete_shader to fail. The problem is that buffer.clear produces Meta shaders, and compile_shader/delete_shader see those. We correctly identify them as internal shaders, but always return INVALID_OPERATION, while the test expects INVALID_OPERATION or INVALID_ENUM.
Actually, the problem is that compile_shader's first subtest assumes that no shaders exist, i.e.
should return GL_INVALID_VALUE because 9 simply does not exist.
But because of Meta, it does exist - and the real bug is that applications can observe and even alter these shaders. In the dEQP test sequence, it happens to be a gl_shader_program, so we return GL_INVALID_OPERATION. But it could be a shader, at which point we would return it.
I have patches to fix this.
