iexMetaHelper Compatibility Notes


From v11.0.0 we simplified the meta-data exporting functionality as follows:
- New TIEMetaListView component to instantly support the display and editing of meta-data
- Replaced all CONTROL.Read*From*() methods with simply WriteTo
- Replaced all CONTROL.Write*To*() methods with simply ReadFrom
- Replaced all *CompatibleFile methods with IEFileTypeSupportsInfo()

Also note that the following legacy method were removed: GetExifTagList(), ContainsExifTag(), ReplaceExifTags(). If you need to support these, define IEIncludeDeprecatedInV3 in ie.inc
