Actual image size by default for size/position filter

This may well be one of those user error things, but whenever I use the size/position filter on an image I check the actual dimensions of the image in a separate viewer and then enter them into the filter’s parametres menu to avoid stretching/shrinking/warping problems. I make any changes required in an image editor before importing so that I don’t need to tweak anything in Shotcut.

It might be nice if those dimensions were automatically populated based on the image specs in each case… or implement a ‘use actual sizes’ button?
