docs(twitter): add 1692565070583136348 corpus (NOTimothyLottes SPC CRT shader on Steam Deck)

4-post thread, 7 images. SPC CRT shader on Steam Deck; not doing subpix render this time but RGB vs BGR order still matters. Comparing grille / bad-convergence-scan / subpix-scan. Non-subpix: 1-pixel RGB separation (intentional bad convergence) to help hide scaling. Subpix: 1/3-pixel separation (less visible misaligned convergence). Subpix wins: 'almost 3x doubling of scanline width detail, just perceptually feels a lot cleaner and easier to reconstruct in the mind.'

+SPC: CRT shader on the Deck. This time not doing subpix render. Yet RGB vs BGR order matters still. One way it becomes possible to simulate even spaced aperture grill (removing scan fx), and the other more of the scan effect.

+
+The non-subpix scan has 1-pixel separation of RGB (intentional bad convergence) to help hide scaling. The subpix scan uses 1/3-pixel separation (less visible misaligned convergence). Pixel as in output pixel.
