[poppler] [PATCH] Improve linear gradients in cairo backend

Hi all, 

when drawing gradients with cairo, we don't need to fill a path for
every region, we can just fill the bounding box with the gradient
pattern, but this only works when shading->getExtend0() ==
shading->getExtend1(), since we can use CAIRO_EXTEND_NONE when they are
FALSE and CAIRO_EXTEND_PAD when they are TRUE. When they are different,
we could just use the current approach, adding a path for every region.
This is exactly what the attached patch does.
