An XtWorkProc that reads a frame of floats when there is nothing else to do.

Make piecewise cubic reflectors
******************************************************************************
Input:
dsmax maximum length of reflector segment
nr number of reflectors
ar array[nr] of reflector amplitudes
nu array[nr] of numbers of (x,z) pairs; u = 0, 1, ..., nu[ir]
xu array[nr][nu[ir]] of reflector x coordinates x(u)
zu array[nr][nu[ir]] of reflector z coordinates z(u)
Output:
r array[nr] of reflectors
******************************************************************************
Notes:
Space for the ar, nu, xu, and zu arrays is freed by this function, since
they are only used to construct the reflectors.
This function is meant to be called only once, so it need not be very
efficient. Once made, the reflectors are likely to be used many times,
so the cost of making them is insignificant.
