Nathaniel LedfordandClaude Sonnet 5.5 2f7d248d61 #323: a window does not keep the whole source uploaded with its stages ...

Profiling a slider drag at 100 % and 400 % found each tick of the window render
taking about 60 ms: the 24 MP source (288 MB) uploaded to the device was kept with
the view's stages, counted against the stage budget, and the stages cleared every
frame, so every tick uploaded and resampled again. A source over 96 MB is now
uploaded for the render only; the stages keep the window's own sampled pixels.
A tick costs 7-12 ms instead. equivalence.rs covers it.
