Change Details

The preview generator waits for everything to have settled a bit and starts a timer of 200ms before generating a preview. This timer was fired everytime when entering a folder needlessly delaying preview generation since it never checked whether the style option actually changed.

This avoids work being done when it doesn't need to be. For instance, the preview generator waits for everything to have settled using a 200ms timer before generating a preview. This timer fired also in response to `onStyleOptionChanged` and needlessly delayed preview generation when navigating between folders despite the style option (e.g. icon size, view mode) not having changed.
