The h2d.Camera instance is now tracked via RenderContext.currentCamera variable. This allows for much more flexible camera visibility filtering other than top-level layer filtering, as objects nested deep in the object tree now will be able to check which camera they are being rendered by during drawRec call and alter/prevent rendering when needed.
Motivation: While filtering by top-level layers works reasonably well, when more complex cases arise, like camera-specific effects nested in the object tree or camera-specific parameters for rendering like tint or alpha - it becomes clear that a way to check current active camera is required.
Additionally updated Camera2D sample:
Fixed regression after Layers.add adding to top-most layer by default.
Added a moving car sprite that uses ctx.currentCamera to filter its visibility as an example of new feature.
