Upscale improvements

[smilesrg]

Is it possible to add parameters for upscale like max[x,y], exact[x, y] and crop? Because currently it is not possible to upscale rectangle image to square with cropping using upscale filter. To achieve this behaviour, I had to downgrade to v0.11.1 and use thumbnails filter with allow_upscale set to true.

I think I'm finding the same issue - that currently irrespective of mode or allow_upscale, smaller images of different aspect ratios can not be upscaled to a guaranteed size and aspect ratio using the thumbnail filter alone.

This chaining seems to work though (makes the allow_upscale redundant):

        core_grid:
            filters:
                upscale: { min: [250, 220] }
                thumbnail: { size: [250, 220], mode: outbound, allow_upscale: true  }

I believe this is fixed already.
