Detailed Description

Stores a generic 2D bounding box.

Although this structure can store a 2D bounding box transformed by any homography, most of the time it stores an axis-aligned bounding box. To retrieve it, do the following:

float x = xform.mat3[0][2];
float y = xform.mat3[1][2];
float w = width  * xform.mat3[0][0];
float h = height * xform.mat3[1][1];
