Fix font regression in AdjustMMParams
Commit 2334660 changed the |dest_width| in CFX_Font::AdjustMMParams to unsigned, but this means that dest_width - min_width becomes unsigned, which is wrong because the subtraction could be negative. This CL fixes this bug. Bug: chromium:845697 Change-Id: I88fb2f3ee3837d80ff5fa70a08309d9e0fec50e0 Reviewed-on: https://pdfium-review.googlesource.com/33150 Commit-Queue: Nicolás Peña Moreno <npm@chromium.org> Reviewed-by: Tom Sepez <tsepez@chromium.org> Reviewed-by: Lei Zhang <thestig@chromium.org>
