Random question from a caffeine addled mind:

If the stitcher was written to use the GPU of a really
fast graphics card -- what would that do to the portability
of the stitcher?  

For example: Enblend (you all know Enblend right?) doesn't
run on my old Win2K machine.  I had to get a special version
of Enblend that was compiled *without* GPU support in order to
run Enblend and thusly Hugin.

Also, I know that Java is going to support hardware acceleration for
its OpenGL and DirectX pipeline but it will disable that acceleration
on certain OS's and graphics cards that don't support specific
instructions.  Don't ask me specifics on this...

So -- if you write a stitcher that utilizes all the features of
a particular graphics card on a particular OS -- you are pretty
much stuck on that combination -- right?
