2017-02-06Fix stream reading from pFile.Graeme Connell
If m_pFile is set, m_bMemoryBased is set to false. However, ReadRawData incorrectly checks if m_bMemoryBased is TRUE before passing a read to m_pFile. This fix changes things to correctly call m_pFile's ReadBlock.

2017-02-06Add support for fill and stroke RGBA in CPDF_PageContentGeneratorNicolas Pena
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.
