Fixed the issue where text bounds found by GcPdfDocument.FindText() methods may be incorrect if a transformation is applied to the page.
Fixed the issue where an exception occured while rendering certain PDFs to images.
Version 4.0.0.632 (Maintenance) - Breaking Changes
Removed WidgetAnnotation.DefaultAppearanceString, FreeTextAnnotation.DefaultAppearanceString, RedactAnnotation.OverlayTextAppearanceString and RedactAnnotation.OverlayTextFormat properties to ensure compliance with PDF specification.
