- OFFSET <ox> <oy>

Indicates a pixel shift (offset) introduced by this pass. These pixel
offsets will be accumulated and corrected during the next scaling pass
(``cscale`` or ``scale``). The default values are 0 0 which correspond
to no shift. Note that offsets are ignored when not overwriting the
hooked texture.

COMPONENTS <n>
Specifies how many components of this pass's output are relevant and
should be stored in the texture, up to 4 (rgba). By default, this value
