From Andre Garneau:

* Fix for the aspect ratio not being properly set when screens have
different aspect ratios.
* Minor fix for makeCurrentImplementation being called directly instead of
makeCurrent() causing the owning thread pointer not being tracked
* Fix for osglauncher so that it sets its update text regions to DYNAMIC to
prevent multi-threading issues.
