RFR: 8315217 JavaFX: make Printer.printableArea(paper) public

[Florian Kirmaier]

We sometimes want to access the printable area for a given paper.
The printable area is currently defined in com.sun.javafx.print.PrinterImpl and we would like to make it accessible to javafx.print.Printer.
We would also return the value in points instead of inches for a more consistent API.


RFE:
I have to create an RFE for it, correct?
Any point of reference, on how to create one?
