### "--blittype": Scaling mode override

Sets the upscale/downscale mode in the engine. By default, the engine uses a linear filter for quality.

Accepted options:

* `--blittype=fastest`: nearest neighbor scaling. Will be blocky, but is the fastest.
* `--blittype=pgpt` : Use linear interpolation. This uses parallel processing to speed up rendering. Note this was the default blitter before 2026.7.3.
* `--blittype=hybrid`: Use a slightly faster linear interpolation engine.
