Changes between Version 2 and Version 3 of Ticket #48842, comment 2

v2	v3
6	6	- Resizing a 4800x2400 image to 300x150 resamples the source. The resampled image is less than 1/3 the size of the original, `$resize_ratio` is `0.09765625`.
7	7
	8	This seems like the cause for #48522 where the sample image (10315px) is up-scaled to 12800px before resizing it to 2560px.
	9
8	10	Setting to high priority as this needs to be reviewed and committed asap :)
