Blitz does some culling of things that are definitely off-screen.

Whatever remains is sent to the graphics card for rendering. But some of this may still be off-screen.

So TrisRendered() can be larger than the actual number of triangles drawn.

If there is a single mesh then it either gets culled or not.
As a result TrisRendered() will report nothing or everything.
