Feature request - control point tab image preview for HDRI

[mkogoj...@gmail.com]

Hello.

When importing EXR into Hugin, the image preview in the control point tab shows the image as generally black whenever there is a strong light source present in the image, e. g. the sun.

This hinders manual placement of control points, when necessary. Images without strong contrasts are unaffected. Control point cursor shows local contrasts normally.

A cause of this could be that Hugin compresses the entire contrast range into an 8bit preview linearly. Adding a strong gamma curve to previews could solve this. The effect appears in the photos tab as well.
