I know I can rotate an image by [rotate] or [rotateXYZ] before [pix_texture].
But I was playing with pix_lumaoffset and I would love for it to work at an angle (currently it's only vertical). This could be done by rotating the pix as a pix, applying the effect, and rotating back.
But it seems there's no pix_ object for rotating?
How would one do this?
