Robert Osfield cd44e63b90 From Cedric Pinson, "I have tried some model that produces crashes in the dae plugin because
of empty node:

if (GetFloat4Param(cot->getParam()->getRef(), f4)) {...}

in the model I have tested cot->getParam()->getRef() return 0x0 and make
it crahes inside GetFloat4Param.

I have added a test before calling GetFloat4Param
if (cot->getParam()->getRef() != 0 &&
GetFloat4Param(cot->getParam()->getRef(), f4)) {...}

BUILD DEPENDENCIES

- COLLADA DOM (document object model) v1.4.1
  http://collada.org/mediawiki/index.php/DOM_guide:_Setting_up

- libxml2

- iconv

A standard "ccmake ." while in the root of the OSG source will expose
two CMake variables: COLLADA_INCLUDE_DIR and COLLADA_LIBRARY. Using
these two variables correctly can be a bit tricky (especially as
the "right" and "wrong" ways to use Collada are hard to define), but
I will briefly explain them below.

  COLLADA_INCLUDE_DIR: This variable wants the path where it can
  find the COLLADA headers. On most systems this will be something
  like /usr/include or /usr/include/collada.

  COLLADA_LIBRARY: This variable is asking for the FULL PATH to the
  file libcollada_dom.a. As long as it can find this file, the
  OSG Collada ReaderWriter should build just fine.
