Universal filter does not respect input pagesize

Hi,

When converting from PS to PDF using cfUniversalFilter, the input file's page size is lost and the output is US Letter regardless.

Minimal example:

/* Build with
 * gcc $(pkg-config --cflags libcupsfilters) main.c $(pkg-config --libs libcupsfilters) -o testps2pdf
 */
#include <stdio.h>
#include <string.h>
#include <stdlib.h>

#include <cups/cups.h>
#include <cupsfilters/filter.h>

int main(int argc, char *argv[]) {
  int input, output, status;
  cf_filter_data_t filter_data;
  cf_filter_universal_parameter_t filter_params;

  input = open("test.ps", O_RDONLY);
  if (input > 0) {
    output = open ("test.pdf", O_CREAT|O_WRONLY, S_IRUSR|S_IWUSR);
    if (output > 0) {
      memset(&filter_data, 0, sizeof filter_data);
      memset(&filter_params, 0, sizeof filter_params);
      filter_data.logfunc = cfCUPSLogFunc;
      filter_data.printer = NULL;
      filter_data.content_type = strdup("application/postscript");
      filter_data.final_content_type = strdup("application/pdf");
      filter_data.copies = 1;
      status = cfFilterUniversal(input, output, 1, &filter_data, &filter_params);
      printf("Printer: Filter status %d\n", status);
      close(output);
    } else {
      close(input);
      return -1;
    }
    close(input);
  } else {
    return -1;
  }
  return 0;
}

Output:
