The upscalers start in about 1 second again.
- The upscalers no longer take ~9.5 seconds to start (0.9.14 to 0.9.16). Each start compiles the motion estimate's shaders, and the search
shader had grown to 6.4 seconds of compile time, from the experimental "Motion by shape" matching, which is off by default but was compiled
for everybody. Until the engine was ready, Lossless Scaling's own NIS showed instead. The plain search compiles in half a second now (its
output is bit for bit what it was), and the "shape" variant is made on a thread of its own, only when "Motion by shape (test)" is
switched on, and takes over once it is ready. (The host testscaler_bgra, which had been failing for this reason, passes again.)
