do not init into fluidrenderer as it isn't even allocated (nullptr)

we'll get back to fluidrendering probably after the qt conversion
fix running gl commands on non-render thread. turns out m_camera->centerOn

does that (i forgot). Was getting called on world::update, but now
lets just do it on ::render. that saves a check for if the renderers
are init'ed as well.
start printing frametime now..apparently we're getting 60-80ms on my

high end system :(

i'm guessing it's some crazies with qmutex(and locker)
