The problem might be when you have some operations that you can
accelerate with the GPU, and some operations that you need to perform
using the CPU. As long as you can assume memory transfers in both
directions are free there is no problem, apart from this hurdle, there
is no reason not do gradually start porting GEGL nodes to use
optional,. hardware acceleration,. sacrificing some quality for speed.
Each node ported would be a separate change,. a wider change would be
to specify the "glitz'ness" as a property of the pixel
representation,. and somehow attempt using that special "blessed"
pixel representation throughout the pipeline,. this is rather
unfeasible IMO
