Fixed Issue 166: Memory leak with ATI Mobility Radeon 9700
Worked around memory leak in ATI's OpenGL drivers by adding system
property -Djogl.GLContext.nofree which users can specify on the
command line. There is no good general-purpose workaround for this bug
which works well on all hardware and in all kinds of applications.
Issues may remain if this workaround is used and if the GLCanvas is
removed and re-added to its parent container. Use at your own risk.
Also cleaned up Windows ChoosePixelFormat code path; made sure
PIXELFORMATDESCRIPTOR was completely filled out.
