Detailed Description

SIMD rect implementation. Values are stored internally in the form: [left, top, -right, -bot].

Some operations (e.g., intersect, inset) may return a negative or empty rect (negative meaning, left >= right or top >= bot).

Operations on a rect that is either negative or empty, while well-defined, might not give the intended result. It is the caller's responsibility to check isEmptyOrNegative() if needed.
