candidate with the check I named
Last iteration I offered the pivot mismatch as a quantified candidate for
the swoosh rendering too thick, and said explicitly that whether it bites
depends on which pivot the compositor uses and that I had not checked. I
checked.
blit takes the drawn size from the TEXTURE and uses the pivot only as the
scale anchor, kf.x minus pivot times scale-minus-100 over 100. At scale
100 that term is zero. And every one of the seven swoosh elements --
ptlogo_back2, its glow and the five eff segments -- reports a single
scale of (100,100) across all its keyframes. So the mismatch, real as it
is in the data, cannot move or resize the swoosh in our render. Refuted,
under my own name.
It is not harmless everywhere, and I have said where it does bite:
ptlogo1 and ptlogo2 run 100, 101, 103, 112, 150 during the build-in, so
there the wrong pivot really does displace them -- during the animation
rather than at rest.
What that leaves is the blend, by elimination rather than by evidence.
Position and size are the texture's own and right, fade is
white-with-alpha, tint is white, the texture is blue-leaning rather than
pink. Seven overlapping sprites at 5 to 23 percent opacity stacked with
plain alpha-over saturate toward opaque white, which is what we draw and
would read as thicker beside the game's thin coloured stroke. Recorded as
the remaining candidate and explicitly not as a diagnosis -- no blend
mode has been identified in the data.
