A new CPDF_PageContentGenerator is created for every call of
FPDFPage_GenerateContent, so having the maps there will cause duplicated
resources to be created every time this method is called. Thus it is better
to move these to the page.

CPDF_PageObject is a CPDF_GraphicStates, which allows us to add graphics
information to the object itself. The RGB can be added easily in the stream.
The alpha parameter needs to be in a dictionary contained in the ExtGState,
which should be part of the page's resources.

See Table 4.9 for path construction operators. Ignoring v, y, because those can
be replaced with the more powerful c operator. The code added will be called by
public methods that do not exist yet.

This patch fixes a possibility that an owned CPDF_Stream is handed to the
indirect object holder inside RealizeResource(). Its arguments are
changed to take an object number, as is done elsewhere in the code, to
suggest that only indirect objects are acceptable.

They won't work with std::unique_ptr down the road, so replace
with std::vector.
