During a number of tests, the user's reaction to the loading indicator displayed after hitting the "Next" button for the first time was to wait. They wouldn't try to proceed to subsequent slides until the indicator disappeared completely. This was aggravated by the change in cursor icon.
To avoid this kind of confusion, the indicator is now just the container's background image. Thus, it is only visible if the current slide is not loaded yet. Previously, it would be shown on top of the current slide throughout the loading process of the first slide or the entire set (depending on the situation). Even if the current slide was fully loaded.
Additionally, the cursor icon remains the same.
Both changes do not affect any of the plugin's options.
