AVPlumber CUDA overlay

Code & setup guide

One base plus fifteen transparent overlays, composed by overlay_many_cuda. Generated labels, alpha ramps and overlapping shapes show layer order and transparency. An independent CPU reference checks every output plane.

Sixteen labelled inputs composed into one 1920×1080 CUDA output.

The complete processing graph

All 50 nodes and 49 queues from the completed 641×360 validation case. Sixteen source branches feed one CUDA composition filter, then raw output for the pixel comparison. CPU/GPU transfers are explicit test boundaries.
