It now takes ~40 seconds to render the test-page on trunk.
Better than 60 seconds but still 40% slower than s_sincos.S.
25.82% libm-2.17.90.so [.] __cos
22.06% libm-2.17.90.so [.] __sin
6.33% libm-2.17.90.so [.] __dubsin
4.59% libpoppler.so.36.0.0 [.] GfxPath::lineTo(double,
double)
4.50% libpoppler.so.36.0.0 [.]
Gfx::doRadialShFill(GfxRadialShading*)
