[point, status] = project(bb, loc, slope, fac)
Projects the data in array bb along the direction defined by
npix = (1/slope)*nlin. Used by sfrmat11 and sfrmat2 functions.
Data is accumulated in 'bins' that have a width (1/fac) pixel.
The smooth, supersampled one-dimensional vector is returned.
bb = input data array
slope and loc are from the least-square fit to edge
x = loc + slope*cent(x)
fac = oversampling (binning) factor, default = 4
Note that this is the inverse of the usual cent(x) = int + slope*xstatus =1;
point = output vector
status = 1, OK
status = 1, zero counts encountered in binning operation, warning is
printed, but execution continues
