             Summary: Add support for selecting different display qualities
                 Key: GUACAMOLE-37
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-37
             Project: Guacamole
          Issue Type: New Feature
          Components: guacamole-client, guacamole-common-js, guacamole-server
            Reporter: Frode Langelo


The current adaptive encoding greatly reduces bandwidth usage and improves the user experience.

It would be great to be able to choose different quality settings for a user inside a Guacamole session, in cases where a user is in a low bandwidth/high latency environment.

Example quality options could be:
High: PNG (normal) / JPEG q90 (adaptive)
Medium: JPEG q90 (normal) / JPEG q60 (adaptive)
Low: JPEG q60 (normal) / JPEG q40 (adaptive)

This feature would involve:
- add UI to select quality
- API to guacamole-server to control quality setting
- plumbing for quality settings in guacamole-server
- handle separate qualities per user (because of session sharing)
- repair of lower quality areas of the screen (from adaptive encoding) with higher quality refresh
