> Splash: Avoid bogus memory error for tilingPattern

Yes, You're true, Fabio: It is this part of SplashOutputDev::tilingPatternFill:

+    if ((unsigned long) result_width * result_height > 0x800000L)
+      return gFalse;

It's quite easy to solve:

    if ((unsigned long) result_width * result_height > 0x10000000L)
      return gFalse;

(which means a new limit of 16384 * 16384 pixel)

BUT: This also means, that Gfx::doTilingPatternFill doesn't wotk correctly with
this sample, because returning false means that Gfx should do the work by its
own.

@Albert: Should I try to solve the Gfx::doTilingPatternFill bug, or can You
live with the new limit?
