Before the current changes, all surfaces were painted using a full-screen overlay, no matter how large the object was rendered. This approach is redundant and required reorganization. At the moment, all objects are rendered using an overlay equal to the box of the object itself, which reduces the cost of filling the surface. Also surfaces and images were divided into different entities, which reduces the pressure on memory. Also geometry data for rendering and geometry data for calculations in system memory were logically separated.
