Background
GdkPixbuf-based image processing can take over 1GB of memory for processing a single high-resolution photo. We've decided to introduce another processor, hoping that it'll improve Morandi's memory profile and performance.
Problems
By default, Vips processor retains the input colourspace when saving, which is inconsistent with how GdkPixbuf's version works
Solution
Cast to sRGB before saving if needed
