Regression: Custom cameras no longer work

[nspitko]

ref 9df4f9d

RenderContext now has it's own camera instance. This ensures any custom camera logic in a subclass is discarded, and forces the use of heaps' default, fairly limited camera logic.

It also immediately calls update(), so even pre-calculated matrices get wiped.

[TothBenoit]

Separating the game camera from the render camera is intended as render logic should not impact the game logic.

You should be able to use your own custom camera by replacing the one in the RenderContext and overriding the load and update methods of your camera. However, I agree that this is an awkward entry point for your camera.

Another way is to override your Renderer and RenderContext to make sure the correct camera class is used.
