Add 3D support for the Mac on Leopard (OS X 10.5) and earlier. This CL uses

FBO rendering with glGetTexImage() into a TransportDIB that is then used as
a texture for rendering the final image in the render view in the browser.
While not optimal, it works and can be optimized later, after the new GPU
process work is completed.

This CL also enables stencil buffer support on the Mac.  All the Pepper3D
demos run on the Mac with these changes.

BUG=none
TEST=3D rendering unit tests.
