Fast switching ICC support

[phototweak]

As is indicated in the dialog, ICC support is "very slow" for large images.

Is there a way to quickly turn it on and off, as with a toolbar button or keyboard shortcut?

Is there a way to make ICC rendering delayed along with the "Use delayed high quality" option?

yes, currently icc is applied on loading so can be slow
