-.. c:function:: bool  glm_aabb2d_frustum(vec2 aabb[2], vec4 planes[6])
-
-    | check if AABB intersects with frustum planes
-
-    this could be useful for frustum culling using AABB.
-
-    OPTIMIZATION HINT:
-       if planes order is similar to LEFT, RIGHT, BOTTOM, TOP, NEAR, FAR
-       then this method should run even faster because it would only use two
-       planes if object is not inside the two planes
-       fortunately cglm extracts planes as this order! just pass what you got!

-    Parameters:
-      | *[in]*   **aabb**     bounding box
-      | *[out]*  **planes**  frustum planes
