Nico Weber 27e369cd19 LibGfx/ICC: Add a one-element cache for CLUT conversions ... Our current CLUT code is pretty slow. A one-element cache can make it quite a bit faster for images that have long runs of a single color, such as illustrations. It also seems to help with photos some (in `0000711.pdf` page 1) -- I suppose even them have enough repeating pixels for it to be worth it. Some numbers, with `pdf --render-bench`: `0000711.pdf --page 1` (high-res photo) before: 2.9s after: 2.43s `0000277.pdf --page 19` (my nemesis PDF, large-ish illustration) before: 2.17s after: 0.58s (!) `0000502.pdf --page 2` (wat hoe dat) before: 0.66s after: 0.27s `0000521.pdf --page 10 ` (japanese) before: 0.52s after: 0.29s `0000364.pdf --page 1` (4 min test case) before: 0.48s after: 0.19s Thanks to that last one, reduces the time for `time Meta/test_pdf.py ~/Downloads/0000` from 4m22s to 1m28s. Helps quite a bit with #23157 (but high-res photos are still too slow).		2024-02-19 07:16:05 +00:00
