Letterbox without oversampling

[andrieslouw]

Hi, is there a way to have letterbox (adding margins to fit the requested ratio) but without oversampling the image if the requested size is larger than that of the original?

@ndavoust : Letterboxing without oversampling is something we probably will implement in the next API (sneak preview here: https://t0.nl/docs/transformation.html#without-enlargement). We're not really proud on the current naming of &t=[fit|fitup|square|squaredown|absolute|letterbox] and will try to streamline and extend the transformations. This will take some time however.

This has been implemented in API version 5 (#189). See:

Please let me know if you run into any issues.
