[qtquick] forward touch events to gecko engine
Make it pass tests for now, because render loop is not established yet
Make sure we don't crash when mMCRenderer is 0
Added more checks for MCRenderer null state
Make qmozviewsgnode and QSGRender render fbo texture when multithreading enabled
Make it render with one FBO target
Don't apply matrix on fbo rendering
Make code more robust and cross platform
Cleanup mcthreadobject
Disable bad render loop, because it works good without it
Make it work with USE_GECKO_COMPOSITOR_THREAD
Make mcthreadobject destroy correctly on quick exit
Make threaded renderer more stable to shutdown
Make it render about:license on start (prepare texture as soon as possible)
Setup seaparate thread for gecko compositor by default
Enabled multi thread compositing for test runner by default
Don't start new render iteration if we about to destroy
