2018-05-08Remove almost all usages of CFX_FixedBufGrow with std::vectorNicolas Pena
Tested by running safetynet_compare.py on this patch vs master. The results were 0 regressions and 0 improvements. The two remaining usages cannot be replaced because they would cause a regression.

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.

2018-05-03Use strict types in FPDF API, try #3Tom Sepez
Rather than messing with actual inheritence, add type-checking wrappers and just blatantly cast to incomplete types. Along the way, this points out places where we would downcast without checking, which I fix.

A subsequent patch will tackle the ad-hoc ref counting, but we can tidy this before going down that hole. Decouple CTTFontDesc creation from face setting. Remove union and treat single-entry case as vector's first element. Pass unique_ptr to prove memory ownership.
