FIX: Allow SVG uploads if dimensions are a fraction of a unit ()
* FIX: Allow SVG uploads if dimensions are a fraction of a unit

`UploadCreator` counts the number of pixels in an file to determine if it is valid. `pixels` is calculated by multiplying the width and height of the image, as determined by FastImage.

SVG files can have their width/height expressed in a variety of different units of measurement. For example, ‘px’, ‘in’, ‘cm’, ‘mm’, ‘pt’, ‘pc’, etc are all valid within SVG files. If an image has a width of `0.5in`, FastImage may interpret this as being a width of `0`, meaning it will report the `size` as being `0`.

However, we don’t need to concern ourselves with the number of ‘pixels’ in a SVG files, as that is irrelevant for this file format, so we can skip over the check for `pixels == 0` when processing this file type.

* DEV: Speed up getting SVG dimensions

The `-ping` flag prevents the entire image from being rasterized before a result is returned. See:
