"auto img = image->Image()" deduced std::vector<int32_t> by value, so every
frame copied the whole detector image before converting it -- 72 MB on a 16 Mpx
detector. Bind a const reference instead.
The sentinel-to-float conversion also ran single-threaded on the GUI thread;
spread it over rows the same way RenderImage does. 18.1 Mpx: 11.8 -> ~1 ms,
plus the copy that is now gone.
