fix typos in README
- fix GLUT/OpenGL include paths for the tools
- fix the build with Clang 3.3 and libcxx (LLVM)
-Fixed some incorrect assumptions about PRT files:

updating openGL code  a bit,  something seems off in 2014 with alpha blending from how it used to work.. need to really rework the point draw stuff eventually anyway.
slightly better at opacity issues..   might have to switch over some stuff  to use the draw  calls from  a locator instead of  shape.
will look into this..
