video_core: temporal upscale stand-in for Fortune's Weave's DLSS
The one-frame blit left 3D edges aliased and shaking: the game jitters
its camera every frame for DLSS to accumulate. Fire Emblem: Fortune's
Weave's first DLSS pass (also rejected) has the motion vectors
(cbuf0+0x290, R16G16) and the frame's jitter (+0x1b0/+0x1b4, in input
pixels). Kepler compute keeps them, and the stand-in for the last
network pass now draws temporal_upscale.frag: input samples placed where
the jitter put them and weighted by distance, blended with the previous
result reprojected along the motion vectors (Catmull-Rom) and clipped to
the 3x3 neighbourhood in YCoCg. The history is copied from the result
right after drawing it, so post-processing the game later applies to its
output does not feed back. EDEN_NX2_TEMPORAL_UPSCALE=0 restores the blit.
