Detailed Description

Bounding area diagram:

+----+ <----U (Upper edge Y value)
|    |
+----+ <----B (Bottom edge Y value)
^    ^
L    R (Left/Right edge X value)

Example structure when subdividing 1 bounding areas: 1 area can be divided into 4 smaller children to accommodate image areas with denser triangle distribution.

lp/rp/up/bp is the list for storing pointers to adjacent bounding areas.
