    .SH "DESCRIPTION"
        .PP Available only in the tessellation control and evaluation languages, gl_PatchVerticesIn contains the number of vertices in the input being processed by the shader. A single tessellation control or evaluation shader can read patches of differing sizes, and so the value of gl_PatchVerticesIn may differ between patches.
