  "message": "[M90-LTS] Use more safe arithmetic in CFX_DIBBase\n\nMost of the calculations are \"safe\" because we know that the DIB\nhas validated sizes before allocating a buffer, and that calculations\nin terms of bytes won\u0027t overflow and will be within the buffer. But\ncalculations in terms of bits might create overflow in temporaries,\nso use safe arithmetic there instead.\n\nRe-arranging the order of operations thus converting to bytes first\nmight be one option, but we want to handle the 1 bpp case.\n\nTest would require large images that might not be possible on\nall platforms.\n\nM90 merge issues:\n  cfx_bitmapcomposer.cpp: conflicting includes, and conflicting\n  declaration of dest_scan\n\nBug: chromium:1253399\nChange-Id: I3c6c5b8b1f1bf3f429c7d377a8a84c5ab53cafd9\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/85510\nReviewed-by: Lei Zhang \u003cthestig@chromium.org\u003e\nCommit-Queue: Tom Sepez \u003ctsepez@chromium.org\u003e\n(cherry picked from commit a8b293732a0160d1bc1d5b0ad5744922f0f820d5)\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/86230\n",
