Inspector color management

[Michael Ezra]

This is an issue that was present since the initial implementation of the inspector.

Images saved in e.g. ProPhoto ICC profile do not show in correct color.

On a side note, thank you for numerous improvements to the inspector panel, these are very useful and great. The focus mask implementation was on my to do list a few years ago, and now its working here:)
