        Behaves similarly to MultiDrawArraysIndirect, except that drawcount defines an offset (in bytes) into the buffer object bound to the PARAMETER_BUFFER binding point at which a single sizei typed value is stored, which contains the draw count. maxdrawcount specifies the maximum number of draws that are expected to be stored in the buffer. If the value stored at drawcount into the buffer is greater than maxdrawcount, the implementation stops processing draws after maxdrawcount parameter sets. drawcount must be a multiple of four.
        Parameters:
        mode - what kind of primitives to render. One of:
        POINTSLINE_STRIPLINE_LOOPLINESPOLYGONTRIANGLE_STRIPTRIANGLE_FAN
        TRIANGLESQUAD_STRIPQUADSLINES_ADJACENCYLINE_STRIP_ADJACENCYTRIANGLES_ADJACENCYTRIANGLE_STRIP_ADJACENCY
        PATCHES
        indirect - an array of structures containing the draw parameters
        drawcount - the offset into the parameter buffer object
        maxdrawcount - the maximum number of draws
        stride - the distance in basic machine units between elements of the draw parameter array

        The depth values of all fragments generated by the rasterization of a polygon may be offset by a single value that is computed for that polygon. This function determines this value.

        factor scales the maximum depth slope of the polygon, and units scales an implementation-dependent constant that relates to the usable resolution of the depth buffer. The resulting values are summed to produce the polygon offset value, which may then be clamped to a minimum or maximum value specified by clamp.

        The values factor, units, and clamp may each be positive, negative, or zero. Calling the command PolygonOffset is equivalent to calling the command PolygonOffsetClamp with clamp equal to zero.

        Parameters:
        factor - scales the maximum depth slope of the polygon
        units - scales an implementation-dependent constant that relates to the usable resolution of the depth buffer
        clamp - the minimum or maximum polygon offset value

        Specializes a shader created from a SPIR-V module.

        Shaders associated with SPIR-V modules must be specialized before they can be linked into a program object. It is not necessary to specialize the shader before it is attached to a program object. Once specialized, a shader may not be specialized again without first re-associating the original SPIR-V module with it, through ShaderBinary.

        Specialization does two things:

        • Selects the name of the entry point, for that shader’s stage, from the SPIR-V module.
        • Sets the values of all, or a subset of, the specialization constants in the SPIRV module.

        On successful shader specialization, the compile status for shader is set to TRUE. On failure, the compile status for shader is set to FALSE and additional information about the cause of the failure may be available in the shader compilation log.

        Parameters:
        shader - the name of a shader object containing unspecialized SPIR-V as created from a successful call to ShaderBinary to which a SPIR-V module was passed
        pEntryPoint - a pointer to a null-terminated UTF-8 string specifying the name of the entry point in the SPIR-V module to use for this shader
        pConstantIndex - is a pointer to an array of numSpecializationConstants unsigned integers, each holding the index of a specialization constant in the SPIR-V module whose value to set.

        Specialization constants not referenced by pConstantIndex retain their default values as specified in the SPIR-V module.

        pConstantValue - an entry in pConstantValue is used to set the value of the specialization constant indexed by the corresponding entry in pConstantIndex.

        Although this array is of unsigned integer, each entry is bitcast to the appropriate type for the module, and therefore, floating-point constants may be set by including their IEEE-754 bit representation in the pConstantValue array.
