This patch does the following things: (1) It removes the legacy page-range-handling function "DetermineWhetherToPrintPage()", and it now will always print every PrintedSheetFrame. (2) It activates PrintedSheetFrame's page-range handling function so that it can take over responsibility for skipping pages during print operations. (3) It adjusts the nsPrintJob code that kicks off individual asynchronous "print the next page" operations (which is now really "print the next PrintedSheetFrame). This nsPrintJob code used to have page-range-related handling interwoven into it, and that handling isn't necessary anymore now that we're handling page-skipping up front at layout time. (4) It replaces the mPageNum member-var (which tracks which page we're about to print or are currently printing) with mCurrentSheetIdx, which is now a 0-based index into the list of PrintedSheetFrame instances. (5) It removes nsPrintData:mNumPagesPrinted, which was only used for progress-bar-completion updates & which basically tracked the same information that I'm tracking in the new mCurrentSheetIdx variable. There's some additional cleanup that we should do after this lands (e.g. some s/page/sheet/ renamings) but I'm holding off on that for now, to keep this patch relatively targeted.
