j3dcore: mark all occurences of GL_SUN_global_alpha as FIXME

The hilarious part is, the JOGL1 pipeline never used this feature anyway as when
it tested for the extension, there was a typo 'gloabl' which meant it never was
counted as available by the Canvas3D class...fun.

Likely this all just needs removing and replacing with vertex(?) shaders, there
is also API that exposes this in the Pipeline interface that should be killed as
it was only to expose this feature:

Pipeline:setGlobalAlpha
Pipeline:disableGlobalAlpha
Canvas3D:setGlobalAlpha
Canvas3D:supportGlobalAlpha
GeometryArrayRetained:disableGlobalAlpha

...and more.
