So should it be faster or slower with with FPWIPF enabled?
Currently, with FPWIPF *enabled*, during digitizing rendering is 66
times worse, whereas outside digitising it is 2-3 times better. This
I have the same behaviour on two machines - x86 Debian testing with ATI
X700 PCIE, using the open source radeon driver, and amd64 Ubuntu Gutsy
with GeForce 6200 LE PCIE, using proprietary nvidia driver. Hardware
acceleration and direct rendering work OK on both machines.
