gdiplus: Disable PNG encoding filters.
This speeds up the encoding process, sometimes at the cost of increased PNG file sizes. PNGs created using gdiplus on Windows 10 have filters disabled, too, according to pngcheck. The application "ZusiDisplay" encodes finished frames in PNG format and sends them through a named pipe for "Zusi 3" to use as an in-game texture, so performance matters for that use case to improve "embedded display" FPS.
