Periodically remove all mesh HW buffers.
Work around for a quirk in Irrlicht where a HW buffer is only
released after 20000 iterations (triggered from endScene()).
Without this, all loaded but unused meshes will retain their HW
buffers for at least 5 minutes, at which point looking up the HW buffers
becomes a bottleneck and the framerate drops (as much as 30%).
Tests showed that numbers between 50 and 1000 are good, so picked 500.
There are no other public Irrlicht APIs that allow interacting with the
HW buffers without tracking the status of every individual mesh.
The HW buffers for _visible_ meshes will be reinitialized in the next frame.
