ah no, this doesn't sound like a good idea.
i'd rather have to force users to switch now than to maintain 2 separate
sets of objects for the rest of Gem's live.
but read on!

i investigated a bit further and have created a fix that should be
totally transparent from the user's pov, by not using wild
reinterpretation-casts but instead using a lookup table where the real
GLuint IDs are mapped to small floats.

this should work (check svn)
