avoid call of bilinear interpolation in case of tilingPatternFill

As I said: in my opinion the bilinear interpolation is not necessary in case of
tilingPatternFill. This patch avoids it and increases the speed of rendering
page 3 on my laptop a little bit:

before:
date; utils/pdftoppm -cropbox -png -r 72 -f 3 -l 3 sample2.pdf sample2; date
Do 23. Mai 13:56:51 CEST 2013
 Do 23. Mai 14:24:27 CEST 2013

after:
date; utils/pdftoppm -cropbox -png -r 72 -f 3 -l 3 sample2.pdf sample2; date
Do 23. Mai 15:15:28 CEST 2013
Do 23. Mai 15:24:17 CEST 2013

Still not well but the best I can do for the moment!
