PdfTilePageIdentity class

Everything about a page's visual state that changes what a tile should contain: the page slot and its epoch/content/destructive stamps (from PdfPageRenderIntent) plus the display plan (paper color, annotations, rotation, from PdfPageRenderPlan). Two identities that compare equal may share tiles; any difference is a distinct key so stale pixels never surface.
