Let me try to explain the motivation for having different methods for
transformations which are tuned for upsampling on the one hand, and
downsampling on the other, and why a "one size fits all stylishly"
scheme is neither easy to put together nor likely to be fast.
Practical explanation:
If one

All the "to be named" samplers can be used for arbitrary warps, and
all can be used for upsamp

Most likely names of the resamplers at this point are either:
upsharp and upsmooth
or
sharpupsize and smoothupsize
for the samplers tuned for warps in which upsampling is more typical
than downsampling (e.g., for image enlargement), and either
downsharp and downsmooth
or

I dislike writing email, and you are almost using email like IRC, feel

In a "scale image" menu, the most likely appropriate method could be
chosen automatically (depending on the requested resizing), with an
"extra smoothing" toggle set by default to off.

Is it "decided" that there will be only two versions of the "good for
upsampling" sampler, and only two versions of the "good for
downsampling" sampler as well?
Because if it is, Eric's nohalo1 and snohalo1 patches could be made
"ready to push" in very little time, and the preliminary version of

i wouldn't want to be bothered with choosing different samplers
for up/down-scaling.
So just let me choose from matching pairs of samplers.
You know them better than i do...

Sure, for most us
Suggestion implementing the s/nohalo family and the nohalobox family
without an explicit, visible, parameter:
Would it be possible/desirable to use the current code (which has a
parameter) as some sort of template?
Then, the nohalobox code would produce four independent samplers:

Adam Turcotte and Eric Daoust are implementing samplers (alternatives
to nearest neighbour, bilinear, bicubic, lanczos... interpolation),
names snohalo1 (tuned for upsampling) and nohalobox (tuned for
downsampling), which both have a natural parameter. This parameter is

I have added a parameter (called blur) to a new sampler, and I want to
pass a value to this parameter when rotating with an XML file.
I know how I would pass a value to the rotation parameters, but how do
I pass a value for a GeglSamplerNohalobox parameter?
Here is an example of a rotation test:
