2018-06-29Better determine if ICC colorspaces can be used for blending.Lei Zhang
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.

This is a manual revert of the CL at: https://pdfium-review.googlesource.com/c/pdfium/+/32159 The only file manually changed was cpdf_renderstatus.cpp Reason for revert: the bug below shows that sometimes the vector size used is larger than the parameter given to CFX_FixedBufGrow.
