Krishty b00de10eb3 Simplified importer search and fixed a few bugs ... The search for a matching importer had a few issues, see #3791. There were two different mechanisms to determine whether an importer accepts a specific file extension: 1. `aiImporterDesc::mFileExtensions`, which was forwarded to the UI via `BaseImporter::GetExtensionList()`. 2. `BaseImporter::CanRead()` when called with `checkSig == false`, which determines whether to actually use that importer. Both were redundant and got out of sync repeatedly. I removed 2. completely and replaced it with 1., thereby syncing UI/import and shortening all `BaseImporter::CanRead()` implementations. Further bugfixes: - fixed glTF2 importer throwing exceptions when checking whether it can load a file - removed `BaseImporter::SimpleExtensionCheck()` because it is no longer used and had a bug with case sensitivity Since the `checkSig` parameter in `BaseImporter::CanRead()` is now useless, it can be removed completely. I’m not sure if this would break ABI compatiblity, so I’ll submit it with a later pull request.		2021-04-24 00:17:50 +02:00
