- Removed some couts.
- Added methods "selectDrawableByRayPicking" and "translateSelectedDrawables()" to class ComoApp. The idea for future versions is to remove method ComoApp::getScene() and only allow management of the scene through the ComoApp class.
- Added signal ComoApp::renderNeeded().
- Added slot ViewFrame::render().
- Connected previous signal and slot, so when the scene is modified, all ViewFrame instances are notified and updated.
- Added attributes to clas OpenGLCanvas for keeping the inverses of that canvas' dimensios.
- As a test, now the OpenGLCanvas allows the user to translate the default scene's cube by keyboard or mouse.
