Projection — projection | Aesthetic

Converts world coordinates to screen coordinates (same space as the 2D canvas). Call from render callbacks (render_2d, render_gui, frame).

Function	Returns
`projection.to_screen(pos[, ignore_frustum])`	Screen `sx, sy`, or `nil` when behind the camera / out of view
`projection.box(min, max)`	Box on screen as `x, y, w, h`, or `nil`
`projection.entity_box(entity_id)`	Entity hitbox on screen as `x, y, w, h` (interpolated), or `nil`

ignore_frustum = true also projects points outside the view (only fails behind the camera) — useful for edge-of-screen indicators.
