Fix for 8025988 breaks jdk build on windows

The fix for 8025988 moves several attributes from class WPrinterJob to class RasterPrinterJob
but leaves them 'private'. This change causes following failure on windows:

g:\work\jdk8.2d\jdk\src\windows\classes\sun\awt\windows\WPrinterJob.java:1835: error: PD_PAGENUMS has private access in RasterPrinterJob
        if ((flags & PD_PAGENUMS) != 0) {
                     ^
g:\work\jdk8.2d\jdk\src\windows\classes\sun\awt\windows\WPrinterJob.java:1837: error: PD_SELECTION has private access in RasterPrinterJob
        } else if ((flags & PD_SELECTION) != 0) {
                            ^

Suggested fix is to make the attributes protected.
