    .SH "DESCRIPTION"
        .PP gl_SampleMaskIn is a fragment language that indicates the set of samples covered by the primitive generating the fragment during multisample rasterization. It has a sample bit set if and only if the sample is considered covered for this fragment shader invocation. Bit B of mask gl_SampleMask[M] corresponds to sample 32 * M + B. The array has ceil(s / 32) elements where s is the maximum number of color samples supported by the implementation.
