org.apache.fop.pdf.PDFPaintingState
This keeps information about the current painting state when writing to pdf. It allows for creating new graphics states with the q operator. This class is only used to store the information about the state the caller needs to handle the actual pdf operators. When setting the state for pdf there are three possible ways of handling the situation. The values can be set to override previous or default values. A new state can be added and then the values set. The current state can be popped and values will return to a previous state then the necessary values can be overridden. The current transform behaves differently to other values as the matrix is combined with the current resolved value. It is impossible to optimise the result without analysing the all the possible combinations after completing.
