As a result, the texture processing pipeline increases the number of texture operations and texture loads that are accelerated relative to the number of texture operations and texture loads that are not accelerated.

An angular displacement is determined between a selected pair of the first and second pairs of screen-space basis vectors and screen-space principal axes of a local approximation of the mapping that indicate the maximum and minimum scale factors of the mapping.
