- Check for pending exceptions after function calls and script executions. - Call LOGERROR instead of JS_ReportError when there is a conversion error in FromJSVal, since that can only be called from C++ (where JS errors don't really make sense). Instead, C++ callers of FromJSVal should handle the failure and, themselves, either report an error or simply do something else. - Wrap JS_ReportError since that makes updating it later easier. This isn't a systematical fix since ToJSVal also ought return a boolean for failures, and we probably should trigger errors instead of warnings on 'implicit' conversions, rather a preparation diff. Part of the SM52 migration, stage: SM45 compatible (actually SM52 incompatible, too). Based on a patch by: Itms Comments by: Vladislavbelov, Stan` Refs #742, #4893 Differential Revision: https://code.wildfiregames.com/D3093 This was SVN commit r24187.
