Working SDL input (keyboard/mouse)
Browse files Browse the repository at this point in the history 
Status: build and runs, keyboard+mouse working, window is somehow oversized but responsive.

Codechanges:
* creating render window via OgreBites::ApplicationContext instead of OGRE Root directly - needed to receive events
* overriding OgreBites::ApplicationContext::createRoot() with our pre-existing setup code, to initialize `mRoot` as expected.
* calling `OgreBites::ApplicationContext::addInputListener()` to receive events.
