public static void DisplayProgressBar(string title, string info, float progress);


Displays or updates a progress bar.

The window title will be set to title and the info will be set to info. Progress should be set to a value between 0.0 and 1.0, where 0 means nothing done and 1.0 means 100% completed.

This is useful when you perform a long blocking operation in an Editor script, and want to notify the user about the progress. Use this method for long operations that make the editor non-responsive. For long operations that happen in the background, use the Progress class instead.

After you display the progress bar, clear it using ClearProgressBar.
