2018-07-02Add pdfium::Vector2D<>()Tom Sepez
Many of the FX_Alloc's that have not been converted to std::vector are using FX_Alloc2D and the safe math it performs under the covers. Make an equivalent function for returning a vector to avoid burdening callers with the safe math equivalents. Use it in one place.

Implement CPDF_ColorSpace::IsNormal() and check it when rendering. While IsNormal() is trivial for most colorspaces, it needs to be implemented separately for ICC colorspaces. This fixes a rendering regression from commit 1c0de38c.

2018-06-20Re-work some more c_str() usage.Tom Sepez
Many of these are converting ByteString => c_str => ByteStringView, since the ByteStringView ctor is implicit. This is unfortunate, since that involves a strlen() which the ByteString already knows if we use AsStringView() instead. This changed one test result where we can now return the string "\0" instead of "" -- since strlen no longer eats the NUL. This seems consistent, say, with String.fromCharCode().
