Overview

The location and size of a rectangle region.

The width and height of a #graphene_::rect_t can be negative; for instance, a #graphene_::rect_t with an origin of [ 0, 0 ] and a size of [ 10, 10 ] is equivalent to a #graphene_::rect_t with an origin of [ 10, 10 ] and a size of [ -10, -10 ].

Application code can normalize rectangles using graphene_::rect_normalize(); this function will ensure that the width and height of a rectangle are positive values. All functions taking a #graphene_::rect_t as an argument will internally operate on a normalized copy; all functions returning a #graphene_::rect_t will always return a normalized rectangle.
