Wish: Add support for GL_EXT FBOs

[Hans L]

Ubuntu 10.04 Lucid
Intel Pentium M 1.7Ghz
chromium-browser 5.0.379.0 (44662) Ubuntu
VGA compatible controller: nVidia Corporation NV31 [Quadro FX Go700] (rev a1)
nvidia-173 drivers

Plugin crashes upon trying to call glGenFramebuffers. This video card supports glGenFramebuffers through GL_EXT instead of GL_ARB, as can be seen in the attached glewinfo.txt

Debug of crash follows:
(gdb) run
Starting program: /usr/lib/chromium-browser/chromium-browser --type=plugin --plugin-path=/usr/lib/mozilla/plugins/liblightsparkplugin.so --lang=en-US --plugin-data-dir=/home/peeps/.config/chromium/Default --channel=26085.0xb5c0d68.173863632
