2018-10-12Remove more unnecessary includes and do IWYU as needed.Lei Zhang
Also move some implementations out of headers. Change-Id: I321fc26970c440d874b135bd28e8bc8156b9afee Reviewed-on: https://pdfium-review.googlesource.com/c/43890 Commit-Queue: Lei Zhang <thestig@chromium.org> Reviewed-by: Tom Sepez <tsepez@chromium.org>

2018-08-24Rename CFX_DIBSource to CFX_DIBBase.Tom Sepez
It is not a source from which you can get CFX_DIBs, but rather a base class from which all DIBs inherit. Do the same thing for the CPDF_DIBSource wrapper class. Mechanical change apart from adding a one-line comment in cfx_dibbase.h Change-Id: Id2bde87813ca301d9fafc55ce08d703dfc6a7184 Reviewed-on: https://pdfium-review.googlesource.com/41352 Reviewed-by: Lei Zhang <thestig@chromium.org> Commit-Queue: Tom Sepez <tsepez@chromium.org>
2018-05-07Use checked large integer in ContinueQuickStretchchromium/3424Ryan Harrison
This existing code has the potential for an integer overflow in it. When overflow occurs in this function scaling may partially succeed. This is due to how out of range values are being clamped, which implicitly swallows the overflow. This CL changes the calculation to be performed in a 64-bit space and then attempts to down cast it back to 32-bit space at the end. Because there are multiple steps it is possible for an intermediate value to cause an overflow in 32 bit space, but the final value to be valid. If the downcast is not possible then the stretch operation is failed. An existing test case has been updated, since it encoded an incorrect result.

Sed + minimal conversions to compile, including moving some constructors into the .cpp file. Any that caused ASAN issues during the tests were omitted rather than trying to resolve the underlying issue.
