  "message": "[Skia] Fix the issue that wrong scale is applied to y position.\n\nIf a glyph\u0027s transformation matrix is [a b c d 0 0], then `a` is\nthe scale factor applied to its x position, `d` is the scale\nfactor applied to its y position, and `b`,`c` are used for skewing\nthe original glyph bitmap.\n\nHowever, when rendering bug_1402, cp.m_AdjustMatrix[1] (AKA `b`) is\nused for scaling the glyph on the y axis, which happens to be 0 and\nerased the glyph\u0027s y position. This resulted in all characters with\nthe same transformation matrix are rendered lower than expected.\n\nThis CL fixes the issue by apply `-cp.m_AdjustMatrix[3]` (`d`) as\nthe scale factor of a glyph\u0027s y position, which takes consideration\nthat the y position is inverted from character to device.\n\nBug: pdfium:1740\nChange-Id: I5ed3d2f36562564ebf1039ec18a7354adee2af87\nReviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/87410\nReviewed-by: Lei Zhang \u003cthestig@chromium.org\u003e\nCommit-Queue: Nigi \u003cnigi@chromium.org\u003e\n",
