The nightly fuzz job found a JBIG2 symbol dictionary that decoded for minutes: each bitmap side may be 65535, and up to 65535 symbols are decoded pixel by pixel. Vendored hayro-jbig2 0.3.0 with two bounds: at most 2^28 pixels per bitmap (also the page bitmap, halftone grid and grayscale image), and at most 2^26 symbol pixels per dictionary. The finding now finishes in about a second. Synthetic regression test (a 65535 x 65535 page and region behind a small /Width and /Height); the corpus sweep shows 0 regressions.
