The shape's angle plus rotation, about its center. Frame/caller origins are additional local source-texel offsets from that center.

update · draw

void update(float dt) override;
void draw(DrawList& draw_list) const override;

bounds · cull_bounds

mattmath::RectangleF bounds() const override;
mattmath::RectangleF cull_bounds(float units_per_pixel) const override;

Unsnapped world geometry, including both authored and caller origin. cull_bounds additionally covers view-pixel quantization at this zoom. Both the geometry and per-pixel padding are cached at construction; this final class exposes no geometry/frame setters. Adding one must refresh both, keeping lookups and trigonometry off the cull path.

rectangle_ (protected)

mattmath::RectangleF rectangle_ = mattmath::RectangleF::ZERO;
