This only loads the shader source once instead of 1000 times. Reduces
the time to first frame by a further 30% by massively reducing the
work the main thread has to do at startup. The Qt3DExtras material
classes are convenient but lead to bad practices like this. We should
provide a way to allow them to share the effect easily but still use
the provided materials for their API. Perhaps a new ctor overload that
takes a QEffect pointer would work nicely.
Also fixed some float vs double vs int precision warnings as a drive
by.

No point loading the same data 1k times. Shaves 35% off the time from
application start to first frame being complete.
