Editor: zooming in to 1:1 somewhat breaks preview

[Former user]

version: 1.3-38-g7f578f388 built with GCC 9.3.0

Something happened to the Editor, especially the zooming, which leads to strange result.

I want to edit a new raw image that was just copied to the system, so there's no arp file present. After opening the file in the editor, the auto matched tone curve is applied:

After zooming to 1:1 it seems like the auto-matched curve is not applied anymore:

Sometimes this happens again after setting the profile back to “Default” and zooming in again.

I might have broken something with my recent commits… thanks for reporting, I’ll take a look

properly refresh the preview when auto-matching is enabled and wb_preview_mode == WB_BEFORE_HIGH_DETAIL

Fixes #87
