It is required to be an array of positive integers. The existing
implementation seems to accommodate non-compliant PDFs where the Size
entry is an integer.

Allows run-time selection of whether to permit JS inside PDF. Previously,
this was a link-time decision only. This requires a little more caution
before we decide that we have the CJS_Runtime, and not the CJS_RuntimeStub
in a few casts.
Adds a kDisableJavaScript option to the form fill embeddertests.
Adds a --disable-javascript flag to the pdfium_test executable.
Also adds a --disable-xfa flag while we're at it.

Currently, one gets data from CPDF_PatternCS via its parent class's
GetRGB(const float* pBuf) method. To squeeze through this interface, the
caller has to pass in a float*, and CPDF_PatternCS::GetRGB() has to cast
it to PatternValue*.
Instead of doing casting, add a specialized GetPatternRGB() method to
CPDF_PatternCS. In its parent class, CPDF_ColorSpace, add AsPatternCS()
so callers can get a CPDF_PatternCS* from a CPDF_ColorSpace*. Change
existing callers to use these new methods.

This CL repurposes the |pVisited| set to ensure CPDF_ColorSpace::Load()
