From 599cd56f535946726bc30e66e7ac483ec91ab6fd Mon Sep 17 00:00:00 2001
From: Campbell Barton <ideasman42@gmail.com>
Date: Sun, 11 Sep 2011 02:50:01 +0000
Subject: minor edits / cleanup - no functional changes. - use 'const float *'
 and array size in some function declarations. - replace macros for BLI_math
 functions INPF, VECCOPY, VECADD etc. - remove unused VertRen.clip struct
 member. - remove static squared_dist() from 2 files, replace with BLI_math
 function len_squared_v3v3(). - use vertex arrays for drawing clipping
 background in the 3D viewport.
