      Currently, a rasterPoolSize of 8192 bytes is used in qpaintengine_raster.cpp. If this is reduced to just 128 bytes, then 3 of the tst_qpathclipper::clip2 tests fail. This indicates that a sufficiently large/complex real-world polygon will fail when it exceeds the larger 8192 byte allocation if used in the same way as those tests.
