thorvg/src/lib/sw_engine/tvgSwRaster.cpp
Hermet Park 8305383989 sw_engine: optimize 64-bit rasterization. 
Write the pixels per 64-bit data.
This optimization can potentially double the performance in the best case scenario.
It's visually noticeable, especially when the resolution is sufficiently large.
