Translate, scale, and rotate reference images with regular tools#39

Also, controls for transparency, contrast, etc.

Absolutely, we are aware that our current interface (with x, y, z, etc) is far from optimal, it’s in our list to improve this with high priority, just a matter of assigning the resources to it. Also you may have noticed that if you make some adjustments to an image and then save it to file, when you reload it it will be positioned at its initial “default” position, and your movements will be lost. This is also something that we are working to implement right away, as it’s definitely not the experience you expect.
Thank you for all your suggestions, they are on point and useful.

Completed, version 1.4.1
