Description
- Avoid intermediate array copy during copying rtt data to UploadingPainter
- Comment out MTLLog.Debug() statements from methods that are invoked multiple times during RenderPerfTest - this improves memory usage shown in JMC as it avoids StringBuilder creation used internally during formatting of the debug string
- Make MTLRTTexture isVolatile() return false - as equivalent to ES2
