The rendering quality of the placeholder image.
If the image is of a high quality and its pixels are perfectly aligned with the physical screen pixels, extra quality enhancement may not be necessary. If so, then FilterQuality.none would be the most efficient.
If the pixels are not perfectly aligned with the screen pixels, or if the image itself is of a low quality, FilterQuality.none may produce undesirable artifacts. Consider using other FilterQuality values to improve the rendered image quality in this case. Pixels may be misaligned with the screen pixels as a result of transforms or scaling.
