Changes:
- Fixed issues that could result in misleading reports of hanging.
- Fixed issue with destroying thread pools that could result in a crash if one of the threads was not successfully created.
- Fixed issue where snapshots were improperly discarded on a freshly resized Play Store image.
- On Windows, more webcams are supported due to dynamic resizing of the camera frames delivered from the webcam, and errors in frame delivery will no longer hang the emulator.
